To be fair, both Uber and Amazon don't *want* to have people working for them in absolutely horrible conditions for little pay. On the contrary, they'd like to eliminate those positions entirely and automate everything. Which really doesn't bode any better for local service people.
OTOH, this shouldn't be a surprise. The computer geeks have already put many, many typists, calculators (people, not boxes), secretaries, drafters, and similar people out of business just as the industrial revolution put many laborers out of a job. Do you really think that self-checkouts and ATMs have increased the number of employees in checkers/teller positions?
Taxi drivers are not going to be happy about self-driving cars, and though it's not possible now, it will be in the future. The bar on what can and can't be done automatically raises each year. Those close to the line need to see the writing. Unfortunately, there are a lot of people who have already been passed by the line and will never / can never catch up to it. It's going to make for a very bumpy ride over the next half a century.
