I think it's too easy to fall into the anecdote trap, and I like the comments with study data, like the Pew Research and Line Research (sequential surveys, even better)...
I also think adoption will depend on "industry." ChatGPT in education for example:
* BestColleges [1] (n=1000) found 43% of college students have used ChatGPT, and 22% have said they used it to help complete assignments or exams.
* Study.com [2] (n=1100) had some crazier numbers. "Over 89% of students have used ChatGPT to help with a homework assignment. ... 48% of students admitted to using ChatGPT for an at-home test or quiz, 53% had it write an essay, and 22% had it write an outline for a paper."
* Interestingly, in K-12, adoption appears to be higher by teachers than students [3]: "Within two months of its introduction, a 51% majority of teachers reported using ChatGPT, with 40% using it at least once a week, and 53% expecting to use it more this year. Just 22% of students said they use the technology on a weekly basis or more."
* In Japan, a recent survey [4] (n=4000) of undergraduate students conducted from Tohoku University showed 32.4% have used ChatGPT. This is compared to about 7% office workers in Japan using ChatGPT on the job [5] (n=13814) in a recent poll by MM Research Institute.
Of course, education isn't the only industry with an outsized impact (although it's interesting in the sense that it's a good temperature check for the upcoming generation, especially if it's something that is so prevalent at colleges/universities).
But there are other industries as well. a16z Games has been doing a game development survey on Generative AI use in games, and their preliminary results [6] are in-line with my personal experience/view into the game industry - that it has already been completely re-aligning/disrupting the production pipeline: "We heard from 243 game studios - large and small - the results were astonishing ... 87% of studios use an AI tool or model in their studio TODAY. 99% of studios PLAN to use the technology in the future."
I think it's worth noting, that while the sources are dodgy, that even if the 100M user number is accurate for ChatGPT, that's only ~2% of global internet users, and do think this is going to change very rapidly however, but no matter how fast it goes, it won't be overnight.
