I do appreciate that I work in an area that is Very Relevant.

At the same time, I really try to stay in my lane as an infrastructure dude. So πŸ€·β€β™‚οΈ

But also: I tend to be less-tolerant of drive-by opinions. If you’re arguing, you should have done some work in the space. Otherwise I will in fact mock you.

FWIW, I do genuinely try to be aware
of the biases that come with work in all those areas. I don’t promise to avoid being snarky tho.

My employment history includes
working in all of: national security,
social media, and artificial intelligence.

So really, I’m sorry, you get what you get.

Oh absolutely. I genuinely think that we’re unlikely to find ourselves in a scenario where there’s nothing productive to do.

I do think that most repetitive or predictable tasks are eventually automate-able. Which is why I advocate and vote the ways I do.

hard way, but it can and does happen.
Good manners indicate that the picnic ought to be shared and that those who arrived by aircraft express awe and respect for the accomplishment of the climbers.
"The point, of course, is that the people who spent days and sweated buckets could also have taken an aircraft to the summit if all they'd wanted was to absorb the view. It is the struggle that they crave.

From β€œLook To Windward” by Iain M Banks” β€” even if you reach a mountaintop by flight, you should respect those who climbed.

I am admittedly someone who would probably go completely nuts without some kind of productive work to do.

That said, I do think that a Star Trek future β€” or even a Culture scenario β€” should be the high-level goal.

Fully automated luxury queer space communism is in fact a good idea.

Mostly thinking of this given that today’s ML systems are trained on ridiculous amounts of human text, and we should therefore expect them to reflect human thoughts and biases. For better and worse.

I’ve been reading/re-reading some of Neal Asher’s Polity novels lately, and one of the interesting notions is that the AI characters consider themselves as extensions of humanity by other means.

(With, of course, disagreement and drama because fiction).

I found this on Twitter many years ago (I wish I could find the source), and I continue to think of it on a regular basis.

TBH such a common story in tech.

And while hilarious, also a good reminder that you should know where your lines are and pay attention to if they’re being crossed.

Out of curiosity, are there particular feeds or news sources you rely on to keep up to date?

I’m feeling like my current list of feeds isn’t capturing the intersection of infra and model training as well as I’d like, and I’m gradually trying to refresh and tune my list.

I mean I’m over 40 and I remember doing this. The building was large, my locker was remote from the classrooms I went to, breaks between classes were short. IIRC during my senior year I didn’t even know where my locker was πŸ€·β€β™‚οΈ

This. I’m not sure I’d make all the same choices, but the BlueSky team has been thoughtful about their technical choices and clearly had the time and freedom to prioritize that.

I’m not qualified to evaluate some of the specific bits of this, eg in linguistics or neuroscience. But it’s definitely a good read and thought-provoking.

On the other hand, if the models enjoy (or understand the concept of) fiction, your novels may have provided a welcome break compared to thousands of pages of reddit comments!

Perhaps not Boring Technology after all A recurring concern I’ve seen regarding LLMs for programming is that they will push our technology choices towards the tools that are best represented in their training data, making it …

A short note that the predictions that LLMs would favor "boring technology" that's over-represented in the training data don't appear to be playing out as expected with the latest models - once you attach them to a good coding agent harness at least simonwillison.net/2026/Mar/9/n...

Look, it's a mess out there and you can react to that mess by deciding everyone else is a moron or you could react to it by deciding most people are trying to get by with a different context than yours and start working the problem. Those are your choices pretty much, can't choose "no mess"

IME Claude (and recent LLMs in general) are good at gathering and providing detail on a *lot* of information.

I think they’re still really bad at producing documentation I’d want anyone else to read. 😬

I use them in a β€œresearch assistant” mode - lots of raw notes that I use to produce real docs.

Cat points out a real problem. Rather than β€œeveryone builds their own custom app” with all the overhead that entails, my working hypothesis is that we’ll see an explosion of what @inkandswitch.com calls malleable software www.inkandswitch.com/essay/mallea...

The article itself is actually decent, and I’d be really interested to hear a Fated Mates discussion on the topic.

The bsky replies/quotes are mostly very shallow, and it’s clear most people don’t really talk to any romance readers. It’s a whole world of its own.

Today is a project day around the house so I’m wearing a silly shirt from work. I feel like this design hits a lot differently than it did when it first showed up in the swag shop in 2019 or so!
