Counterpoint:
That’s impressive, and these guys are at the cutting edge, but notice it’s on flat, predictable terrain. I bet it couldn’t handle an uncharted bush. And, if the robots want to maintain themselves, much more than walking is required.
As for the FLOPs thing, their techniques are proprietary and bespoke, so it’s entirely possible they’ve used a similar amount of resources to get to this point, even if we can’t know.
I don’t think the ground robots are quite ready to navigate sense bush, swamps, cross rivers, etc., no.
But the majority of the world’s population is easily reachable by flat and predictable terrain right now. And if it really can’t manage to get inside the habitat or attack it with anything else, you’ll be starved out and die off before the robot does.
That’s a good question actually, how long could this thing walk around a city before it gets caught on something or wedged in a corner or otherwise disabled?
