If babies had developed enough muscles they would most probably injure or kill themselves by doing something just like that (as they have no (or very little) control over them)
Good point. And that's just another reason why that entire video seems so wrong. Maybe the ragdolls need to learn to move one step at a time as well, instead of flailing all over the place from the start, without any achievements at all in the end really.
Also, as for the 4 legged, if you have ever seen kittens or puppies come splashing out, they learn to move around extremely quick from a slow pace, without beating up their siblings and mother as their legs are(n't) flying around. I would feel pretty bad for any mammal mother if babies did that inside them.

Not necessarily my beliefs, but I think it is better to ask why, instead of taking one answer to heart. Apply that to nazi's and a million other chaotic moments in history, that the 'why' question was more of a taboo.

Sorry. I would prefer a PM system actually, instead of adding topic counts for single comments, but that makes too much sense for here.
Ontopic:
Anyone else have any other similar (or alternate) AI movies they can share since this topic is growing plenty of interest?
