Hi and welcome to AI SE! You say "All the walking robots look like idiots now." Can you please link us to a video/reference that shows that all walking robots walk like idiots, which is possible? Anyway, I assume you're talking about real-world robots, given that you show us a video of simulated robots walking more or less normally.

See the Atlas by Boston Dynamics. He kinda looks like an idiot in some parts of this video: https://www.youtube.com/watch?v=rVlhMGQgDkY :) I think the road from simulation-to-physical is not a trivial one. There are probably some hard challenges to tackle from a mechanical perspective. Otherwise, programming an agent to do bipedal walking in a simulated environment doesn't seem to challenging to me and is probably straightforward via genetic algorithms.

This has been a mystery to me.
