OpenAI has 900 million weekly active users. So around 0.01% are having problems. That's actually way less than population level measures for the same symptoms on a bigger percentage of people relative to the US on just suicidal ideation alone.
I'm pretty sure that ~100% of those 700 million people will have a bad, utterly dehumanizing experience when they will next be looking for a job, because OpenAI is heavily used by HR.
That's the problem with AI safety. Not in voluntary usage, but in involuntary usage, where someone with power over you will use it against you, it does something incredibly stupid and you have no recourse, no appeal, no awareness of what you did wrong - or if you even did anything wrong.
And it's not just employment. Governments, vendors, retailers, landlords, utilities are, or will all be using it in situations that will dramatically impact your life.
The numbers are inflated considering the topic. There is a lot of anon, api and enterprise traffic that doesn't play any role in this. If you also account for "better search experience" users, then the numbers will probably drop massively.
So the question is how many users engage in intimate conversations at all.
