I was an ignorant, arrogant dipshit too when I was young. Thank God no one gave me the power to do the damage these young men did.

Both of the options here are human writers. The first option is unprocessed human writing and the second option is human writing run through a language model to reproduce the same outputs with different words

If it couldn't have existed without training data, it isn't creating anything at all.

SV pretty much had to invent AI right about now because after moving all valuable info to Slack you need a fucking superintelligence to find anything.

"But don't you want to see cancer cured?"

Of course! It's already taken many beloved people from my life and will likely take my own based on my family history. I don't think AI solves the crux in cancer and think it's telling that much $ behind it supported an admin that killed promising research

To be clear I am not a Doomer and think most prominent Doomer are whack jobs whose cognitive deficits are partially responsible for getting us into this mess.

I see a lot of AI influencers confusing AI adoption rates with AI opinions. They are not the same. I use AI every day for work but hate it. I think it's effective enough that its usage is necessary to be competitive as a SWE but I expect AI to make life worse for most humans including myself.

This is one of the most vile things I've ever heard. Treating humans as though their value is in their economic worth is the root of all evil.

i have to wonder what kind of future AI hypebeasts are imagining when they say stupid shit like, "most or all of white collar tasks will be automated within 18 months". like, okay, microsoft, then who are your customers? who is purchasing O365 subscriptions when robots are doing all the work?

Imagine you work in AI alignment or safety; are receptive to the possibility that AGI, or some sort of broadly powerful and disruptive version of artificial-intelligence technology, is imminent; and believe that a mandatory condition of its creation is control, care, and right-minded coordination at corporate, national, and international levels. In 2026, whether your alignment goal is not letting chatbots turn into social-media-like manipulation engines for profit or to maintain control of a technology you worry might get away from us in more fundamental ways, the situation looks pretty bleak. From a position within OpenAI, surrounded by ex-Meta employees working on monetization strategies and engineers charged with winning the AI race at all costs but also with churning out deepfake TikTok clones and chatbots for sex, you might worry that, actually, none of this is being taken seriously and that you now work at just another big tech company
- but worse. If you work at Anthropic, which at least still talks about alignment and safety a lot, you might feel slightly conflicted about your CEO's lengthy, worried manifestos that nonetheless conclude that rapid AI development is governed by the logic of an international arms race and therefore must proceed as quickly as possible. You both might feel as though you - and the rest of us β€” are accelerating uncontrollably up a curve that's about to exceed its vertical axis.

This is genuinely fun stuff to think about and experiment with, but the people sharing Shumer's post mostly weren't seeing it that way. Instead, it was written and passed along as a necessary, urgent, and awaited work of translation from one world
- where, to put it mildly, people are pretty keyed up β€” to another. To that end, it effectively distilled the multiple crazy-making vibes of the AI community into something potent, portable, and ready for external consumption: the collective episodes of manic acceleration and excitement, which dissipate but also gradually accumulate; the open despair and constant invocations of inevitability by nearby workers; the mutual surveillance for signals and clues about big breakthroughs; and, of course, the legions of trailing hustlers and productivity gurus.
This last category is represented at the end of 26-year-old Shumer's post by an unsatisfying litany of advice: "Lean into what's hardest to replace"; "Build the habit of adapting"; because while this all might sound very disruptive, your "dreams just got a lot closer"
The essay took the increasingly common experience of starting to feel sort of insane from using, thinking, or just consuming content about AI and bottled it for mass sharing and consumption. It was explicitly positioned as a way to let people in on these fears, to shake them out of complacency, and to help them figure out what to do. In practice, and because we're talking about social media, it seemed most potent and popular among people who were, mostly, already on the same page. This might explain why it has gotten a bit of a pass β€” as well as a somewhat more muted response from the kinds of core AI insiders whose positions he's summarizing β€” on a few things:
Shumer's last encounter with AI virality, which involved tuning a model of his own and being accused of misrepresenting its abilities, followed by an admission that he "got ahead of himself"; the post's LinkedIn-via-GPT structure, format, and illustration…

I also suspect that a robust world model is a precondition for quality fiction writing. If you cannot picture where you your characters are in space relative to each other and other stuff, your writing is going to be nonsensical.

Ms. Hart has become an A.I. evangelist.
Through her author-coaching business, Plot Prose, she's taught more than 1,600 people how to produce a novel with artificial intelligence, she said. She's rolling out her proprietary A.I. writing program, which can generate a book based on an outline in less than an hour, and costs between $80 and $250 a month.

Oh she’s a scam artist, got it! Every single time you hear about a person offering coaching in one of these pieces they’re just a scammer and the media falls for it

The Fireside Tapes

There are a number of efforts to preserve old footage and stories from the Chicago hardcore, emo and punk scenes of the 90s and early 2000s that are very exciting. One is The Fireside Tapes Youtube channel with early Midwest emo shows from the Fireside Bowl.
