You can stop being part of the problem if you do it. The problem still exists, but you are no longer part of it. You reduced it by more than your fair share. While the problem would stop existing if everyone made the same choice, there's no pretense that that's actually going to happen. LLM companies are not being excused by such an unlikely hypothetical.
j-lb also made an argument to not care much about LLMs at all, but it was separate from the "skip a day of meat" argument. That's where the big multiplier comes in. But again, separate argument.
I don't want to argue about the example ratio he used. The real ratio is very big if the numbers cited earlier are correct. So if you're going to sit here and say 2000x might as well be arbitrarily large then I think you just joined the "LLM resource use doesn't matter" team, because going by the above citation 2000x is in the ballpark of the correct number, so LLM use is 1 divided by arbitrarily large, making it negligible. Congrats.
