ChatGPT has been useful at work but it hasn’t made me 10x as fast. Maybe 5% and in the area of searching for information. Generating code is terrible: it creates plausible looking code with subtle bugs. Probably OK for API call examples though but nothing algorithmic.
Nonproliferation is really hard to do with software.
Of course, it's also been nice having a semi-intelligent personal assistant and what sometimes amounts to better search.
