Why is using AI for roleplay bad?

It's something i'm wondering since i delated my Janitor AI account becouse while i understand it can get addictive to the point of people developing psychosis or leaving their relationships behind i don't really think these people have been doing well or been mentally healthy before they used AI. More that AI just made it visible

Sure, you could argue about the environment with me but most people with this argument don't even know what data centers are used for outside of AI. Most environmentalist would rather talk about what you can do to help the environment then what you shouldn't do

I grew up pretty isolated from childhood on so i always gravitated towards fanfiction and i'm pretty sure i wasn't using AI chatbots back then simply becouse it wasn't a thing. When i encounter posts about why-you-should-not the argument is most of the time because i'll end up ditching my friends. Except i have no friends to ditch becouse i had a fallout with my whole group becouse my friends ex was hitting on me and she got resentful towards me for his actions... Ah, yes. I already hear it's whole group so "i must be the problem" common argument in online spaces these days. Makes me want to talk to people less

So my question is when is it a toy and when is it a problem?
