The real problem is that it becomes an erotica platform like OnlyFans or Tumblr. reddit, X, Google somehow manages to "red light" that kind of content. Many platforms like Imgur and Pinterest have to ban it or they'd turn into an erotica platform. My wife won't let me use something like WeChat because it's a way to find nearby prostitutes, and this social exclusion turns it into a prostitution app.
I still think ChatGPT is at serious risk of becoming that. It's enough of a brand name that people are actually working with it, but it's losing ground to Claude and Gemini as a serious work tool. Gemini has distribution; Claude has quality. OpenAI is a product app and the GPT-5 release made it clear that their demographic wants companionship.
