The big downside of this will be that conversations exactly like this will be so much more rare. Two real people who are really interested in the same niche thing. That just doesn’t happen much face to face.

Yes I agree, and its a reason I find the current build-out of online ad-tech to be particularly scary: it is built to quietly identify and exploit our biases.
In the conversation around "what might an AI-driven future look like?", I think we need to carefully consider not only the dangers inherent to the AI itself, but also the dangers inherent to having an AI exist in parallel to other systems that open up potential for abuse. Because as-is, it seems like we're heading into a future of AI-driven advertising, that will likely be incredibly effective at playing our inherent biases without our knowing. "Genuine conversation" will be increasingly difficult to identify.
