Yah, without any evidence to back it up my personal suspicion is that we'll arrive at a local maxima of "full self driving on highways and instrumented roads" in ~20 years. I think the area has a lot of potential, but so much of the hype (and stock price) is tied up with "a car that can drive better than a human everywhere" which seems impossible for anyone to produce. Just like with IoT we'll eventually arrive at a boring, useful state...it will just take a while.
