But they work pretty bad from their shareholders perspective since they generate loss on every ride. Even if they avoid all the legal landmines, they still might have to shut down for the simple reason of running out of money (and shareholders running out of patience).

My prediction is that Uber and Lyft will either themselves morph into something more like traditional cab companies, or their technology will be bought out of bankruptcy to build something similar. The world will run out of suckers who want to lose money subsidizing their rides and suckers who are willing to wear out their vehicles to drive for them.

What does that have to do with "good technology" though?
