Probably because we see stuff like this every decade. Ten years ago no one was ever going to drive again because self-driving cars were imminent. Turns out a lot of problems can be partially solved very quickly, but as anyone with experience knows, solving the last 10% takes at least as much time as solving the first 90.

Right.. but self driving cars are here. And if you've taken Waymo anywhere it's pretty amazing.
Of course just because the technology is available doesn't mean distribution is solved. The production of corn has been technically solved for a long time, but doesn't mean starvation was eliminated.
