you seriously underestimate how badly SO MANY people understand anything technological. Getting the pc on and logging in is probably an achievement to some. And so many seem completely incapable of learning or even being curious about how things work. They wouldnt understand to “not keep history” or even that there might be settings to the thing. And add some mental illness to the mix and you get complete disaster.

All they see is a thing that responds to what they write in intelligent seeming way and that is enough to convince them that its completely sentient, some probably doubt the people who keep telling them that its not. Maybe some even think they are being lied to when told llm isnt sentient. Even if you added some mandatory notification that tells that llm isnt sentient, some still wouldnt believe it.
