You are actually right.
I'm fairly gregarious, and find it fairly easy to approach strangers (if I have to). Yes, a lot of human contact can be had for fairly cheap.
However, I'm also aware that this is far from "normal" -- the average person is not this way (at least, not today). How/why things have come to be this way, I cannot pinpoint, but our lives have gotten progressively busier to the point where many of us choose convenience over "richness/fullness of experience".
However, my point is still valid, in that if you are an average person today, the prevailing social gestalt in America is "mind your own business, and don't talk to (or approach) people in the street".
Yes, weird folks like me, who are willing to be more vulnerable (what if the person you just said "Good morning!" to cusses you out?) will be able to get human contact for cheap, but high-quality Human contact is definitely waning.
P.S. Also agree with you that GenAI (and other modern technologies) are providing a frictionless existence, while also removing the richness and meaning that comes with the friction. It's the "soma" from Huxley's "Brave New World".
