I'm definitely open to being worried about... pretty much everything in the general AI/autocratic state proximity... but I'm not sure what specifically you are getting at here. That is, I can imagine an AI that is snooping on everyone. And I can imagine various forms/communications being leaked to authoritarian states. Plenty to worry about!

But, even if an AI convinced me it wasn't sentient, I'd still not trust it to keep things secret for me. I mean, I assume the little "self help" chatbot thing at work could be reviewed by HR if they wanted to.
