They're actually wearing onesies to emphasize the fact that they have become enfeebled.

And they become infeable because there's no purpose in being able to do anything, at least in this conception.

You know, Wall-E is not the future that we want.

It's an interesting question, right?

Why humanoid robots?

One of the reasons, I think, is because in all the science fiction movies, they're humanoid.

So that's what robots are supposed to be, right?

Because they were in science fiction before they became a reality, right?

So even Metropolis, which is a film from 1920, I think, the robots are humanoid, right?

They're basically people covered in metal.

You know, from a practical point of view, as we have discovered, humanoid is a terrible design because they fall over, right?

And, you know, you do want multi fingered hands of some kind.

It doesn't have to be a hand, but you want to have, you know, at least half a dozen appendages that can grasp and manipulate things.

and you need something, you know, some kind of locomotion.

And wheels are great, except they don't go upstairs and over curbs and things like that.

So that's probably why we're going to be stuck with legs.

But a four-legged, two-armed robot would be much more practical.

To some extent, yeah.

But I mean, our dogs manage perfectly well to navigate around our houses and streets and so on.

So if you had a centaur, it could also navigate, but it can carry much greater loads because it's quadruped.
