Thanks, that study is really useful.
It does however suffer from the (maybe insurmountable?) problem that "AI" is an extremely vague term with many potential interpretations.
I expect the "AI experts" in that study may have had a different definition in mind than the general public.
I remain much more skeptical about the impact of AI image/video/audio generation on society than I do LLMs, but LLMs themselves have such a wide array of potential uses that their impact will vary wildly depending on what they're being used for.
