If you think of interacting with another human as a chore, then it will be a chore. But if you think of it an an opportunity to learn, then it can be very rewarding I think.
Honestly though, I don't see the need for tipping to make people interact with each other. I've been taking uber for years (both in southern California and Singapore) and I don't see the need for this.
I've been taking Uber for...5-6 years at this point, with hundreds of rides, and this is emphatically untrue. If this is happening to you, it's probably has less to do with Uber drivers than it has to do with you. (Not that that's an unambiguously negative thing: being able to reliably have interesting conversations with strangers is hardly a required skill).
Your personal experience is just as valuable as mine, but claiming that my opinion is 'incorrect' is probably a bit over the top. :P
"Everywhere I travel, tiny life. Single-serving sugar, single-serving cream, single pat of butter. The microwave Cordon Bleu hobby kit. Shampoo-conditioner combos, sample-packaged mouthwash, tiny bars of soap. The people I meet on each flight? They're single-serving friends."
I use Lyft, which has had in-app tipping for a while now. In DC, most of the Lyft drivers are chatty. Last time I visited SF, none of the drivers were chatty.
