So, to summarize, 900 mathematicians signed a letter basically saying "stop AI from doing math so that our jobs can stick around."
But for anyone who spends more than 5 seconds thinking about what unlocking the equivalent of a billion Fields Medalists would do for humanity, the benefits dramatically outweigh the costs.
Math abundance will help solve chips, medicine, fusion, and numerous other things that will improve the lives of billions, and save millions of lives.
I mean, there was a 0% chance of OpenAI (or any other AI lab) slowing down, so it's a moot point anyways.
But it just seems extremely selfish.
