I don't know why you're being down-voted, it's a valid question.
Computers have eliminated a lot of jobs over the last 30 to 40 years. For example VisiCalc, did a lot of what many tax accountants charged for. It used to be that humans, mostly women, switched (or routed if you will) phone calls.
Automation certainly does eliminate many jobs. But interestingly it also seems to make previously impossible things possible. For example, if we still used humans to switch phone calls, we'd need far more humans then are available. And I don't mean looking for work, I mean everyone could be working a switch board operator and it would not be nearly enough.
On the down side, many people speculate that our tax laws have become as complicated as they have, partly because tax prep software makes it possible to still do your taxes for relatively cheap.
Driver-less trucks will certainly suck for truck drivers, I can just see that History channel show taking a sad turn as more and more of its real life stars are slowly replaced by self-driving trucks.
But what possibilities will it create? Could cars, or for that matter trucks, become like a subscription? You just subscribe and then if at any point and any where you need a ride, you just dial a number and a few minutes later a dirverless vehicle arrives to take you anywhere.
The same could work for goods. Request as much trucking capacity as you need, minutes before you need it. The trucks just show up.
How many hours total (everyone's added up) hours sitting in traffic could be eliminated if a clear majority of the cars are intelligent and networked? Thousand? Millions? All that previously unproductive time, now productive.
All the lives saved from accidents, will they create jobs?
