Even before AI, the human social internet was loaded with bots and disingenuous actors. You want the imperfect human internet that is also pristine and curated. I've been socializing on the internet since 1994, and I feel fairly confident in sharing that this never existed, except in nostalgia.
If that's what you're pining for, you're going to have to find a highly protected part of the internet that is walled off from untrusted actors. However, that's always been the solution, and AI doesn't change that.
