I think we need to differentiate between “AI uses a lot of water!” (not necessarily bad on its own) and “AI stresses local water supplies” (a potentially real issue). The distinction is important because even “modest” use can cause serious issues, especially given the locations of data centers

I will simply be the millionth person to say that an LLM is made up of a bunch of servers owned by a company. OpenAI is committing crimes in broad daylight, and we're all supposed to collectively act like we don't understand this because computer or whatever.

Good articles that are illustrated with AI slop exist. There's also an infinite supply of good articles, so I need to decide quickly what to read and what to ignore. The probability of finding text slop with image slop is very high, so pardon me for ignoring your hard work if you taint it with slop.

This is a canary resuscitator, which miners would use to revive canaries that had passed out from toxic gas, because ideally not only do you care, you don't even leave the bird behind. just a little mining history and not at all a furious scream

If your computer does illegal things, you are responsible. If your computer does illegal things because of what your customer does with it, there’s laws for that too. That whole please regulate AI is such bullshit. Except perhaps it’s time copyright law is actually enforced

I really hate the framing of these stories as "an AI agent broke out and hacked something." No, an inadequate sandbox meant that a powerful and unpredictable computer program was set loose on the open internet by the company that designed it. The agency isn't with the "AI agent", it's with the firm

Sometimes you look at an old HTML document and see some weird tags and snippets from bygone eras. I've complied many legacy HTML bits I've noticed and documented what they were and why there were present. Many of them are rather obscure. Satisfy your curiosity: vale.rocks/posts/html-r...

This was evidenced recently when a paper in a leading chemistry journal had to be retracted because the authors appeared to have used an AI tool to draft part of the publication. The tool used the phrase “mass killing of an ethnic group” as an alternative for “final solution”, though the paragraph in question appeared to be about a zinc nanogel.

1. Donate to climate protection. 2. Reduce you personal emissions. If you get serious about it, it changes how you see consumption and society. Others apologize to me for flying now; this is not just an individual thing, it spreads! 3. Join protests. Start with the next big one, they're fun & safe.

Some people read this as if people using "generative AI" don't know what's up. But these lines just show how the "AI" industry keeps cycling through terms hiding the same systems in order to not have to admit that the invest and outcome don't match.

To me it's really simple: the emissions of free AI use only happen because of the paying users. No paying users → no revenue → no investment → no money → no training → no inference → no data center user → no emissions www.kooslooijesteijn.net/blog/how-muc...
