My guess is that it's not only about "external" improvement but also "internal". Externally, your centaur design is more stable and probably easier to design.

My guess is that it's not only about "external" improvement but also "internal". Externally, your centaur design is more stable and probably easier to design. It would also allow you to do some (highly specific) tasks that a boring, two-legged human could not do. Like Aimee Mullins said in her TED talk[1], this would make you not so much "disabled", but rather "super-abled". Internally, however, you also want those using the exoskeleton to regain their feeling of belonging. That is, you don't want the to "just" walk - you also want them to walk exactly like everybody else. To quote from this book [2], "You don’t always feel inferior, mostly just out of place. Sometimes though, you feel a pang in your chest, a bit like a short, sharp stab. You know what it is instantly… It's there to remind you – you’ll never be quite the same, never on the same level, you’ll never have quite the same opportunities, the same privileges, the experiences and the rites of passages everyone else takes for granted. (...) Like when you go shopping and people stare. Funny thing is, you get used to this one over time, it affects you far less than it does your friends. They hate it and stare back or make comments – “why are people so rude, you’re not a circus animal?”. You feel like saying “actually, I am” but it wouldn’t help, you just want to shop."
