ChatGPT is full of sensitive private information and spits out verbatim text from CNN, Goodreads, WordPress blogs, fandom wikis, Terms of Service agreements, Stack Overflow source code, Wikipedia pages, news blogs, random internet comments, and much more.
I would disagree that AI knows nothing. I use ChatGPT plus near daily to code and it went from a hallucinating mess to what feels like a pretty competent and surprisingly insightful service in the months I have been using it. With the rumblings of Q* it only looks like it is getting better. AI knows a lot and very much seems to understand, albeit far from perfect but it surprises me all the time. It is almost like a child who is beyond their years in reading and writing but does not yet have enough life experience to really understand what it is reading and writing…yet.
