They've always been on the wrong. Will never happen on a mass level. One of the biggest frauds and over hyped products/ideas ever. The taxi driver craze will also hit a wall, as companies like Uber are not profitable, and cannot possibly be profitable. Those who drive for Uber and Lyft, when they tell their insurance companies that they drive for them, they have to then pay 1K to 1.5K per month in insurance, so they end up not telling them. Self driving cars, and college educated people all of the sudden dreaming of being taxi drivers are two things that will unravel in lots of ways.
Society was fine without both, and neither are fundamentally sound, either financially, or practically. Some version of Uber will always be around, as long as they don't have to turn a profit, but sooner or later the well runds dry there, and what you will have is a bunch of unofficial "jitny" drivers on some app, who will drive you somewhere for 20 bucks.
