This sapling is twice as large as it was a week ago, which was twice again as large as it was the week before. Why, at this rate, it'll be bigger than the whole world in but a month.

Waymo provides a tech demonstrator in a closed circuit, and you can pay to ride their demonstrators in select areas of select cities. It's not half bad, let's be honest, but having these limits puts them to a point very far from "self driving cars are here". Even Tesla isn't there with their camera only subsystems and "if you crash you keep both pieces" policy. It's another tech demonstrator you can buy.
If we accept your point that "self driving cars are here", we should accept that Fusion energy is a solved problem because WEST tokamak held plasma for 22 minutes, electric propulsion is a solved problem since we have electric trains for a long time, and Hyperloop is fully operational because I have scale model in my backyard which carries thousands of ants every day.
If the tokomak was energy positive for those 22 minutes, there was more than one of them, and they were running it multiple times a day then I would say it is. But it's not. I'm not sure why you have this need to lump them together. Fusion is quite a different problem, with yet to be solved materials science problems and control systems issues. I'm not claiming that fusion's here, and also I don't think quantum computers are gonna be here anytime soon.
