Wow, a few years ago, if you've shown me this and Genie 3, I'd assume there were at least 10 years of development between them. This looks worse than Doom.
The rate of change is insane these days. I remember Sora launching and thinking "wow" and within weeks it looked like hot garbage.
I'm pretty sure that got debunked as a handful of overfitted examples that fall apart as soon as you leave the area that was 3D recorded. Google's new tech is on another level entirely.
