A lot has been written about "ai", decades and generations ago. I'm not sure if anyone considered the impact on human emotions in a manner that's toxic and widespread. I'm just thinking of a future story where a portion of the population are so traumatized by conversations with machines that they escape their realities in various ways. People talking with computers as if they're human seems very dystopian from the start. The next ten yers is going to be wild.
But also, this is a damn good start to the Thought Police. Imagine if a government gained access to these logs. Actually, I'd be surprised if the US govt didn't already have access to twitter. They're already cracking down on free speech that criticizes them / him.
