4 legs, cables, ... it's already tricky to navigate a complex space on 2 legs without cables ...

I feel like this is close to https://rodneybrooks.com/why-todays-humanoids-wont-learn-dexterity/ recent piece, namely that, yes, all that is easy to imagine but in practice, to reach the seemingly basic level of movement an average human can do for a similar weight, not 1 ton, is actually ridiculously hard. Biological organisms aren't magical by any stretch of the imagination but somehow to manufacture an equivalent is not something we are able to do. Each extra wire adds a bit more weight, which in turns needs more powerful servos, themselves making the one below requiring more power too and keeping the whole thing mobile needs a very powerful battery... so yes making design suggestion is easy but fully comprehending the consequences of those choices often means going back to the drawing board.

Fun fact : VR players know quite well what moving while tethered means. I can tell first hand, it's damn annoying BUT if you don't manage it, you will both fall and break your system.
