Waarom werknemers hun persoonlijke administratie op het werk doen Er duikt regelmatig een opvallende statistiek op in onderzoek naar werk en productiviteit: werknemers besteden gemiddeld **ongeveer 90 minuten per dag** aan hun eigen administratie. Belastingzaken. Afspraken regelen. Verzekeringen aanpassen. Formulieren invullen. Accounts herstellen. Vaak gebeurt dat gewoon tussendoor, tijdens werktijd. Voor werkgevers lijkt dat in eerste instantie een productiviteitsprobleem. Maar het kan ook een aanwijzing zijn dat er iets anders speelt: dat onze digitale systemen verrassend veel frictie bevatten. ## Waarom persoonlijke administratie zo veel tijd kost Veel administratieve taken zijn inhoudelijk helemaal niet zo ingewikkeld. Het gaat meestal om relatief eenvoudige handelingen: een formulier invullen, een wijziging doorgeven, een afspraak maken. Toch voelen deze processen vaak complex en tijdrovend. Dat komt omdat digitale administratie zelden uit één handeling bestaat. Het is meestal een reeks stappen: * de juiste website vinden * door verschillende schermen navigeren * documenten verzamelen * informatie invoeren * foutmeldingen oplossen En bijna altijd speelt er nog iets anders mee: **digitale identiteit**. ## Eén account, één persoon Vrijwel alle digitale diensten zijn gebouwd rond hetzelfde uitgangspunt: **één account – één persoon – één operator.** Daarom bestaan er wachtwoorden, sms-codes, two-factor authentication, biometrische verificatie en apparaatcontroles. Vanuit veiligheid is dat begrijpelijk. Systemen moeten zeker weten dat degene die iets doet ook daadwerkelijk de eigenaar van het account is. Maar dat ontwerp heeft ook een keerzijde. In het dagelijks leven handelen mensen voortdurend namens elkaar. Partners helpen elkaar met administratie. Kinderen regelen zaken voor hun ouders. Vrienden of collega’s helpen met formulieren. Online werkt dat vaak minder soepel. ## Delegatie wordt administratie Waar iemand in het dagelijks leven simpelweg kan zeggen: “Kun jij dit even regelen?”, ontstaat online al snel een reeks extra stappen. Mandaten. Autorisaties. Nieuwe accounts. Verificatiecodes. Delegatie verandert zo gemakkelijk in een extra administratief proces. Dat helpt misschien verklaren waarom veel mensen hun persoonlijke administratie juist op het werk doen. Daar zitten ze toch al achter een computer, hebben ze documenten bij de hand en kunnen ze stap voor stap door het proces gaan. Het zegt dus niet alleen iets over gedrag, maar ook over hoe digitale systemen zijn ontworpen. ## Een ontwerpprobleem van het internet Wat hier zichtbaar wordt, is een kleine maar fundamentele spanning. Het internet is sterk ontworpen rond **individuele identiteit**. Het dagelijks leven functioneert juist vaak via **samenwerking en delegatie**. Die twee logica’s botsen regelmatig. En zolang digitale systemen zo sterk gekoppeld blijven aan individuele accounts en persoonlijke verificatie, blijft administratie moeilijk te vereenvoudigen of uit te besteden. Niet alleen voor mensen. Maar ook voor technologie. ## Een interessante vraag voor de toekomst Dit maakt persoonlijke administratie op werktijd misschien minder verrassend dan het lijkt. Het is niet alleen een kwestie van discipline of tijdsmanagement. Het kan ook een signaal zijn dat onze digitale infrastructuur nog niet goed aansluit op hoe mensen hun leven organiseren. Waar frictie zit, ontstaan vaak nieuwe ideeën en oplossingen. Maar voordat die oplossingen er zijn, is het misschien eerst de moeite waard om het onderliggende probleem goed te begrijpen: hoe digitale identiteit en delegatie zich tot elkaar verhouden. Daar zou weleens een belangrijk ontwerpthema voor de komende jaren kunnen liggen.

Werknemers besteden opvallend veel tijd aan hun eigen administratie tijdens werktijd. Dat zegt misschien minder over gedrag dan over hoe digitale systemen zijn ontworpen.

The Delegation Problem of the Internet But a surprising amount of modern work is not limited by knowledge, tools, or intelligence. It is limited by identity. The small rituals of logging in, confirming codes, verifying accounts, and proving, **again and again** , that you are you. ## Quick takeaways * Many digital systems assume that **only the account holder can act**. * Real life, however, runs on **delegation** : partners, colleagues, assistants, children, caregivers. * Two-factor authentication and identity checks make delegation difficult or impossible. * The result is a hidden productivity drain: **identity management work**. * The same constraint also limits what AI agents can actually do. ## The delegation gap In ordinary life, people constantly act on behalf of others. A partner renews insurance. A child handles paperwork for parents. An assistant arranges travel or contracts. A colleague submits documents. This is not exceptional behaviour. It is how daily life functions. Yet most digital systems assume something else entirely: one account, one person, one operator. Security systems reinforce this assumption. Passwords, two-factor authentication, biometrics, device verification. Each action requires the account holder to appear and confirm themselves. This works well for security. But it quietly breaks something else: **delegation**. ## Identity work Because of this design, a surprising part of modern life is spent performing small identity rituals. Logging in. Entering codes. Approving notifications. Verifying devices. These steps are individually trivial. Collectively they form a kind of invisible labour. You might call it **identity work**. It is the administrative layer that sits between intention and action. ## The AI paradox This constraint also explains something curious about AI. AI systems are increasingly capable of planning, analysing, and organising tasks. In principle they could handle many everyday administrative jobs. But they usually cannot. Not because they lack intelligence. Because they lack **authorised identity**. The real systems where action happens, _banks, government portals, insurers, utilities_ , are locked behind personal authentication. So the human remains the final operator, approving and executing steps that machines could otherwise handle. ## When delegation becomes administration Some systems attempt to support delegation through formal mandates or authorisations. But these often turn delegation itself into another administrative task: registering permissions, managing expiry dates, renewing access codes. The effort required to delegate can become almost as large as the task being delegated. ## A missing piece of digital infrastructure What seems largely absent from today’s digital world is a simple capability: **safe, temporary, and limited delegation of digital authority.** The ability to say: * this person may manage this account for a period * these actions are allowed, others are not * access can be revoked at any time Corporate IT systems have such mechanisms. Everyday digital services rarely do. ## Closing reflection For decades we have focused on making information easier to access and process. But productivity may increasingly depend on something more mundane: How easily we can **act on behalf of one another** in digital systems. Real life is cooperative. The internet, in many places, still assumes **we operate alone**. While everyone debates hybrid working, many firms are missing the real productivity killer. It’s not where people work. It’s the mental load they bring with them. Is your team working or are they… | Elvis Eckardt RecruitmentWhile everyone debates hybrid working, many firms are missing the real productivity killer. It’s not where people work. It’s the mental load they bring with them. Is your team working or are they quietly “life-adminning” on your payroll? New workplace data suggests the average UK professional now spends up to 90 minutes of the workday dealing with personal admin. Energy suppliers. GP appointments. Insurance renewals. School logistics. The modern workday is increasingly interrupted by the second shift of life management. And in 2026, some forward-thinking UK SMEs are testing a radical fix: Employer-sponsored Life-Admin Support. Instead of another wellbeing webinar or free fruit basket, companies are partnering with concierge services that handle everyday personal admin for employees. Why? Because burnout is increasingly driven by technostress and constant cognitive overload, not just workload. The results from early adopters are interesting: Measurable increases in deep work time, fewer mid-day distractions, lower burnout among mid-career managers In other words, a focus strategy. The most valuable employee benefit might not be a pay rise that gets swallowed by fiscal drag. It might simply be time and mental space. If companies don’t help employees manage their lives they’ll keep doing it during the workday anyway. Curious where people stand on this: Business owners: Would you trade the annual summer party budget for a service that handles your team’s life admin for a year? Employees: What would you value more, a 2% pay rise or a life concierge that gives you your evenings back?LinkedInElvis Eckardt Recruitment

Modern life runs on delegation. Yet most digital systems assume one account, one person, one operator. Passwords and identity checks quietly block automation.

Apple’s Pages, Numbers and Keynote: Strong Tools, Weak Culture ## Quick takeaways * Apple’s productivity apps are technically strong but socially marginal * The iWork identity has faded into a broader creative subscription layer * Core features remain free, premium features signal a freemium shift * Microsoft and Google built institutional gravity; Apple did not * Productivity tools become dominant through shared culture, not design alone ## A quiet repositioning Pages, Numbers and Keynote have always lived quietly inside the Apple ecosystem. Free, preinstalled, stable, and tightly integrated across devices. Recently, Apple refreshed them visually and repositioned them inside its broader creative subscription layer. The old “**iWork** ” framing has largely disappeared. In its place sits a more expansive, creative umbrella. At the same time, subtle freemium dynamics have emerged. Core functionality remains free, but premium templates, content and AI-assisted features sit behind subscription tiers. This is not a radical shift. It is a tonal one. And tone matters. Apple Creator Studio ## Strong tools, thin culture Technically, these apps are not weak. Pages handles most document work with calm elegance. Keynote remains one of the most fluid presentation tools available. Numbers is unconventional but capable. If you are already fully inside the Apple ecosystem, they feel coherent. Sovereign even. But professionally, they remain marginal. No one says, “We are a Pages-based organisation.” The difference is not capability. It is cultural gravity. ## Lock-in without institutional weight Microsoft 365 became dominant because organisations standardised on it. Google Workspace reshaped collaboration norms in the browser. They built certification tracks, compliance layers, administrative tooling, shared templates, training ecosystems. Excel became a language. Docs became a habit. Apple did not build that institutional layer around its productivity suite. The lock-in exists at the hardware and ecosystem level. It does not extend into organisational culture. ## The freemium signal The move toward a broader creative subscription model reinforces this positioning. Freemium works well when tools are personal, creative and modular. It works less well when the goal is institutional standardisation. By placing Pages, Numbers and Keynote inside a creative services story, Apple implicitly signals that these are complements to a creative ecosystem, not competitors in enterprise infrastructure. That may be strategic clarity rather than weakness. 💡 What is ****Apple Creator Studio****? Apple Creator Studio is Apple’s broader creative subscription layer that bundles professional tools such as Final Cut Pro, Logic Pro and Pixelmator Pro, while Pages, Numbers and Keynote remain free at their core; certain premium templates, content libraries and AI-assisted features are available within the paid tier, and the older “iWork” branding has largely faded from public positioning, reframing these productivity apps not as a standalone office suite but as part of a wider creative ecosystem. ## The missing identity Apple excels at product identity. The Mac has identity. The iPhone has identity. Final Cut has identity among creators. Pages and Numbers do not. The iWork label once gave them at least a collective name. With that fading, they risk becoming functional utilities rather than cultural artefacts. There is no manifesto for them. No visible professional tribe. No shared productivity philosophy attached to them. Without identity, even strong tools remain peripheral. ## A personal tension There is a quiet temptation to consolidate everything inside the Apple ecosystem. It feels aesthetically coherent and technically integrated. But collaboration reintroduces gravity. Where do your clients work? Where do your peers exchange templates? Where is collective knowledge compounding? That is where culture forms. And productivity without culture rarely becomes dominant. Apple Creator StudioWith an Apple Creator Studio subscription, get intelligent tools in Final Cut Pro, Logic Pro, and Pixelmator Pro, plus premium productivity content.Apple

Apple’s Pages, Numbers and Keynote are polished and free, yet rarely dominant. The issue may not be features, but culture.

From text to diagrams: working with Mermaid <p>There is something interesting about turning text into diagrams.</p><p>Not illustrations, but diagrams that express structure: flows, dependencies, sequences. This becomes especially noticeable when the text itself is not prose, but something closer to a script. Ordered sentences that describe relations rather than tell a story.</p><p>That is roughly the space where Mermaid sits.</p><h2 id="text-as-structure-not-as-explanation">Text as structure, not as explanation</h2><p>Mermaid is usually introduced as a way to generate diagrams from text. That description is accurate, but incomplete.</p><p>What matters more is that the text is the primary artefact. You are not drawing shapes. You are describing relationships. The diagram is a rendering of that description, not the other way around.</p><p>Because of that, the process is reversible. You can always go back to the text, adjust it, and regenerate the diagram. Nothing is lost in translation.</p><p>This is different from most visual diagramming tools, where structure slowly dissolves into manual layout decisions. Once you start dragging boxes around, the model lives in your head rather than in the artefact. Mermaid keeps the structure explicit.</p><div class="kg-card kg-callout-card kg-callout-card-blue"><div class="kg-callout-emoji">💡</div><div class="kg-callout-text"><b><strong style="white-space:pre-wrap">What is Mermaid?</strong></b><br />Mermaid is an open-source, text-based diagramming language created around 2014 by <b><strong style="white-space:pre-wrap">Knut Sveidqvist</strong></b>. It allows you to describe diagrams such as flows, sequences, and state machines using plain text, which can then be rendered into visual diagrams. Mermaid is not a formal standard governed by a standards body, but it has become a widely adopted de facto standard in documentation and developer tooling, much like Markdown. Its focus is on expressing structure rather than visual design, which makes diagrams easy to edit, version, and regenerate. This text-first approach is also why Mermaid works particularly well with modern language models, which can read, generate, and modify Mermaid syntax directly.</div></div><h2 id="low-resolution-by-design">Low resolution, by design</h2><p>I tend to think of Mermaid in the same category as <a href="https://hoeijmakers.net/markdown-google-docs/" rel="noreferrer">Markdown</a>.</p><p>Both are intentionally low-resolution formats. They do not try to look good. They try to stay readable, portable, and precise. You can open them in any editor, version them, diff them, or move them between systems without friction.</p><p>That constraint is not a drawback. It is what makes them durable.</p><p>The result is usually good enough visually, but strong in terms of meaning. For thinking, that trade-off is often exactly right.</p><h2 id="what-changes-with-language-models">What changes with language models</h2><p>What makes Mermaid more relevant now than it used to be is that large language models understand it natively.</p><p>They can generate Mermaid diagrams from descriptions, modify existing ones, or explain what a diagram represents. That lowers the threshold for working with structured diagrams, especially when you are still figuring things out.</p><p>You can start with a rough explanation, ask for a diagram, adjust the structure in natural language, and iterate. The diagram becomes part of the thinking process rather than a final documentation step.</p><figure class="kg-card kg-image-card kg-card-hascaption"><img src="https://hoeijmakers.net/content/images/2026/01/Mermaid-Chart-in-ChatGPT.jpg" class="kg-image" alt="" loading="lazy" width="1920" height="1080" srcset="https://hoeijmakers.net/content/images/size/w600/2026/01/Mermaid-Chart-in-ChatGPT.jpg 600w, https://hoeijmakers.net/content/images/size/w1000/2026/01/Mermaid-Chart-in-ChatGPT.jpg 1000w, https://hoeijmakers.net/content/images/size/w1600/2026/01/Mermaid-Chart-in-ChatGPT.jpg 1600w, https://hoeijmakers.net/content/images/2026/01/Mermaid-Chart-in-ChatGPT.jpg 1920w" /><figcaption><span style="white-space:pre-wrap">Mermaid Chart GPT in </span><a href="https://hoeijmakers.net/tag/chatgpt/" rel="noreferrer"><span style="white-space:pre-wrap">ChatGPT</span></a></figcaption></figure><h2 id="a-tighter-feedback-loop">A tighter feedback loop</h2><p>If you connect Mermaid generation into your workflow, for example via an MCP setup or similar tooling, that loop tightens further.</p><p>You explain something.<br />You get a diagram.<br />You adjust the structure.<br />You regenerate.</p><p>No redrawing.

Kobo and Kindle solve different problems For a long time, I treated Kobo and Kindle as roughly the same thing: e-readers with different ecosystems. Only when I started using them side by side did it become clear that they are built around very different setups. Not different features. Different models. Once you see that, the choice becomes much simpler. ## Two ways of getting content to a reader With Kobo, the device is the centre. You connect it to a computer, copy files onto it, and that’s where they live. The book is on the device, and the device is the destination. The cloud, if you use it at all, is secondary. With Kindle, the account is the centre. You don’t really put files on the device. You send them into Amazon’s system, and the device pulls them down. The book lives in the cloud first. The Kindle is one of several ways to read it. That single difference explains most of the experience. ## Kobo: device-first, edge-based Kobo works best when you treat it like a quiet, durable object. You put books on it deliberately. They stay there. Reading position and annotations live on the device. With tools like Calibre, you can run it almost entirely outside Kobo’s ecosystem. It has more friction. Often a cable. Often a computer. But that friction fits long-term reading. It assumes you care about the book, want to keep it, and might return to it. Kobo feels like a library. Connecting My Kobo Directly to an iPhone 16 ProI connected my Kobo e‑reader to my iPhone 16 Pro with a USB‑C cable. It worked instantly. No adapter, no fuss but just a quiet moment of satisfaction.Rob HoeijmakersRob Hoeijmakers ## Kindle: account-first, cloud-operated Kindle works best when you treat it like a service. You send documents to your account. They appear wirelessly. They sync across devices. You read them, and you can remove them again without much ceremony. That makes it ideal for: * PDFs * Reports * Business books * Things you read once or twice It also means you depend on Amazon being there. The system only really works because Amazon operates it end to end. Kindle feels like an inbox. Reading Webpages on Your Kindle: A Simplified ProcessReading online articles on your Kindle made easy: follow our steps to simplify, convert, and transfer webpages from iPhone effortlessly.Rob HoeijmakersRob Hoeijmakers ## One extra thing that matters: screens Kindle is not just an e-ink reader. It’s a delivery system. The same document can be read: * On e-ink, quietly and with low energy use * On a phone or tablet, with colour and zoom * On a desktop screen, where layout really matters That is especially useful for professional PDFs. Many of them are designed visually, with columns, charts, and typography doing part of the work. With Kindle, you can switch between those forms without changing how the document is delivered. Kobo doesn’t really do that. There, the device _is_ the destination. ## Where I landed Once I stopped trying to make one device do everything, it became obvious. * Books I want to keep live on the Kobo. * Documents and work-related reading go to the Kindle. Kobo is where books stay. Kindle is where documents pass through. The devices didn’t change. My expectations did. * * * Electronic paper and digital ink explainedWhy are electronic paper and digital ink so gentle to the eyes and why is it that these screen consume so little energy.Rob HoeijmakersRob Hoeijmakers

AI literacy: from definition to practice AI literacy rarely shows up as a skill gap. It appears when organisations need to justify decisions, manage risk, and remain accountable.

Word of the year: model When I looked back at the words that kept appearing in my work this year, one stood out more than I expected: _model_. Not because it felt central or dramatic, but because it was everywhere. In AI, obviously. In strategy documents. In conversations about organisations, processes, responsibility. Even in fairly ordinary moments. The word kept resurfacing, quietly doing work. At some point I realised I was using it constantly without really stopping to think what I meant by it. And the more I tried to pin it down, the more elusive it became. Not vague, but flexible. Almost suspiciously so. This piece is an attempt to understand that flexibility. Not to define _model_ , but to ask: how did we get here, and why does this word fit so many domains so well? 2025 Wordcloud for my blog ## The everyday meanings we hardly notice If you search for _model_ , you will likely land on fashion models first. Photo models. People. That might seem like a distraction, but it is actually a useful starting point. A model here is an example. Something you look at in order to orient yourself. This is what it looks like. This is what it could be. We use the word like this all the time. A role model. A model student. A model answer. In all these cases, the model is not a description of reality, but a reference point. It reduces complexity by embodiment. Instead of rules or explanations, you get an instance you can copy, approximate, or respond to. Alongside this, there is another everyday sense that feels more abstract. Scale models. Maps. Diagrams. Calendars. Dashboards. These are not things you imitate, but things you use to navigate. They deliberately leave things out so you can act. A map is not the territory, but it is still indispensable. Already, the word is doing two different jobs: showing what something looks like, and helping you move through complexity. That tension turns out to be important. ## A small detour into etymology The word _model_ comes from the Latin _modulus_ , a diminutive of _modus_. _Modus_ means measure, manner, way, method. Not an object, but a way of doing something. A pattern that makes action possible. _Modulus_ is a small measure. A manageable unit. This matters more than it might seem. From the start, a model was not meant to be the world in miniature, but a chosen scale. A way of handling something too large, too complex, or too messy to grasp directly. A model is already an admission: we cannot deal with everything at once. That quietly underpins almost every use of the word today. Model - Etymology, Origin & Meaning“likeness made to scale; architect’s set of designs,” from French modelle (16c., Modern… See origin and meaning of model.etymonline ## Two paths that never really split Historically, _model_ developed along two closely related paths. On the one hand, the model **as exemplar**. A sculpture model. A pose. A prototype. Something you look at and emulate. On the other hand, the model **as representation**. A plan, a sketch, a proportional guide. Something that captures relationships rather than appearance. These were never cleanly separated. A sculptor’s model was both something you looked at and something you built from. It guided action without claiming to be the final thing. That dual role has always been there. The confusion around _model_ today is not new. It is inherited. ## From craft to science When science and mathematics adopted the word, they did not change its meaning so much as tighten it. A mathematical model is a reduction of reality, expressed in symbols, designed to preserve certain relationships while ignoring others. An economic model does the same with incentives, behaviour, and constraints. These models are explicit about what they leave out. They are tools for thinking, not claims to completeness. This is why scientific models are always accompanied by assumptions, boundaries, and caveats. Not because they are weak, but because their strength lies precisely in being limited. They help you see a system. They do not pretend to be it. ## When models start to build things Engineering shifts the balance. Here, models are no longer only aids to understanding. They become instruments of construction. A blueprint is a model. A data schema is a model. A software architecture is a model. **Change the model, and you change the system.** At this point, the model stops being merely epistemic and becomes operative. Errors are no longer just misleading. They propagate. This is where the stakes rise, and where the word _model_ starts carrying real authority. Not because it is more accurate, but because it has consequences. ## Language models sit on the fault line This long history helps explain why _model_ feels so overloaded in AI. A language model brings all these meanings together. It is a statistical reduction of language, trained rather than reasoned into existence. It produces exemplars: plausible sentences, answers, styles. It is deployed as an operational system. And it is used by people as a way to explore, understand, and make sense of domains. It is, at the same time: something that generates behaviour, and something we use to think with. This collapses an old distinction between models that help us see systems and models that are systems. No wonder the word feels unstable here. It is being asked to do everything at once. Much of the current confusion around AI is not technical, but semantic. We slide between treating the model as a tool for exploration and treating it as an authority. Between using it as a map and mistaking it for the territory. The word _model_ quietly enables that slide. Model Cards, System Cards and What They’re Quietly BecomingWhat are AI model cards, and why are they becoming the documents regulators will turn to first? I read a few and it taught me more than I expected.Rob HoeijmakersRob Hoeijmakers ## Why this word keeps appearing Looking back, I think this explains why _model_ surfaced so often for me this year. It is a word that allows us to work with complexity without fully resolving it. It lets us act, decide, and build while acknowledging that what we are doing is partial and provisional. At the same time, it carries a risk. A model can easily stop being a choice and start feeling like reality. Especially once it is embedded in systems, dashboards, policies, or software. The problem is rarely the model itself. It is forgetting that it is a model. Seen this way, _model_ is not just a technical term, but a cultural one. It sits at the boundary between understanding and authority, between representation and action. That is probably why it is almost everywhere now. And why it is worth pausing over, at least once, to ask what we are really doing when we invoke it. Not to pin the word down, but to keep it honest.

When your Apple ID gets banned… Last Friday, Paris Buttfield-Addison posted 20 Years of Digital Life, Gone in an Instant, thanks to Apple, which kind of blew up. > A major brick-and-mortar store sold an Apple Gift Card that Apple seemingly took offence to, and locked out my entire Apple ID, effectively bricking my devices and my iCloud Account, Apple Developer ID, and everything associated with it, and I have no recourse. Yeah, effectively, they got a $500 Apple gift card, tried to add it to their account, and this triggered a high enough severity fraud alert in Apple's system that it automatically locked their Apple account. Not good. The post is a good reminder of how tied to these large companies we really are. I assume most people reading this post have an Apple account, and it's a good exercise to consider how much of your digital life would become inaccessible if you suddenly lost access to that account. Would you lose all your photos? All of your contacts? All of your files? Obviously, the odds of you losing access to your Apple account are exceptionally low, and Buttfield-Addison's experience is the exception, but I think it is a good reminder that completely benign behavior can occasionally lead to serious consequences you would not see coming. This leads me to three main thoughts on the topic. First, companies like Apple and Google have over 1 billion users, and their automated systems are likely correct far more often than they are wrong, and I don't think they need to go away. However, a good appeals process is necessary to have, and what happened in this person's case is not ideal. How would someone without a blog and ability to reach an audience have gotten this solved? Second, when you're locked out of your Apple ID, you should be able to download effectively everything from your account. This would mean that if I was locked out of my Apple ID, maybe I wouldn't be able to use it or add new data to that account. But if I still was able to authenticate, I should be able to download my photos, my files, and other relevant information that I may want to get out. This would make it so that even if I wasn't able to get the attention that this person did and resolve the issue, at least I could still get a backup of my information. And third, I strongly think that everyone should have some level of redundancy in as much of their digital life as they can. Photos are the big one that I think everyone should be considering. A lot of the things on my computer can be replaced or recreated if they're lost, but not my photos; I can never recreate those moments that I've captured. I personally treat Apple Photos as my de facto photo library, and it works great, but for many years, I had Google Photos also backing up those images, which gave me a second online backup. In the event that my Apple ID was locked, I would still have all of my photos in Google. Since getting a Synology NAS last year, I've actually switched that to having the Synology Photos app automatically back up my photo library to the NAS so that I have local access to all of my photos. Now those photos aren't tied to any online account, they're literally on a hard drive in my house. Consider what's important to you and figure out a solution that works for you. * * * This story has a happy ending, with Buttfield-Addison posting an update yesterday: > We’re back! A lovely man from Singapore, working for Apple Executive Relations, who has been calling me every so often for a couple of days, has let me know it’s all fixed. It looks like the gift card I tried to redeem, which did not work for me, and did not credit my account, was already redeemed in some way (sounds like classic gift card tampering), and my account was caught by that. Obviously it’s unacceptable that this can happen, and I’m still trying to get more information out of him, but at least things are now mostly working. Great news, but again, would someone without a blog and a few thousand social media followers have been able to get here? I don't know…

Why AI Image Editing Is Often Rebuilding AI can make true pixel edits, but many image “fixes” work by reconstruction. Typography and colourisation expose where rebuilding replaces editing.

AI image editing is often regeneration, not editing.

The model recognises the image and recreates it with changes, instead of working on the original pixels.

Seen this way, many artefacts make sense. Typography is usually the first giveaway.
