The prosperity of technology basically solves the problem with the most terrible hardware possible.
For example, if you have a really good microprocessor that works, what you should do is shrink it until it barely works or speed it up until it barely works to get a similar version for cheaper or faster version for the same price.
Same goes with cars. If you have a car that works with ultrasonic and lidar and cameras, eliminate the expensive sensors and reduce the cost.
Reducing the cost will let more people afford the cars, and sell more cars.
To Musk that is basically his plan all along - to replace ICE cars with EVs. Just wish we could keep turn signal/wiper/headlight stalks.
