Robots are already figuring out your personality
I worked at a university donations call center for a while in college. I asked graduates (a lot of graduates) for money (usually not a lot of money).
By and large, people were friendlier than you'd expect, considering I'd be calling them at 9:30 p.m. and requesting they open their wallets for a place many were still in debt to. Could be worse. But here's what made the gig occasionally nerve-wracking: you never knew which kind of person you were calling. The phone would ring, and you'd wait for a voice to apparate, not sure whether you'd be getting the kind older gentleman, the brash young businessman, or something in between.
