> Companies gravitate towards cheap, and maximally efficient labor… currently the best way to achieve that if you’re a US business is to outsource it oversees, ergo India and customer support.

Who do restaurants still have waiters/waitresses if you can just order the food on the tablet at the table? Probably because some research shows the average person going out to eat is probably a certain age and wants the "human experience" and might "undersell" (not get upsold) if they just order themselves. Might get frustrated and order less.
