I would consider paying $150-$200 / month for chat.openai.com access, especially if it continued to improve. It is an astonishing tool for learning and productivity. December 1, 2022 will be a day we all remember.
I agree. I haven't felt this excited by a new technology since the WWW. I can already solve hard problems with it which otherwise would require hiring consultants or spending inordinate amounts of time doing research. It's absolutely game changing.
(I am extremely bullish on probabilistic productivity tools)
