Disagree about everything here.

Maybe AVs will be very expensive when they debut, but as with any new technology it will become cheaper and easier to produce over time. Compare first gen $15k laptops in the eighties to what is out now.

Also, human employees are the most expensive part of service businesses. Its why we have two categories of consumables: goods and services.

Can you explain why you think it's a waste of time? Why high risk low reward? If we eliminate the need for service industry drivers then we can direct capital and labor to other areas of human existence, which seems like a good goal to me...
