It's not so different from an electric wheelchair, the major difference is that your eye-line isn't crotch height. Plus, there's no reason they cannot add some type of haptic feedback. It doesn't even need to be natural or realistic as the body/ brain will adjust.
I'm a disabled person myself (I prefer to use crutches as the world isn't built for wheelchairs, that's another topic). I've been injured since 2012 and they now feel like an extension of myself (a little like having really long arms, I use them to push buttons/ switches and grab stuff). Now trying to walk without them feels VERY alien (and I often fall over if I put too much weight on my injured leg). With crutches; I walk faster than most people (they have suspension!), can climb stairs easier than somebody who is obese, even on days I can't even put my foot on the ground let alone weight-bear. The biggest limitation is the lack of hands to carry stuff.
The point I was making is that while aids/ devices may seem primitive and a poor substitute for what they're trying to replace, the difference they can make to an individual can be huge!
Repairing nerve damage is one of the last frontiers of modern medicine, but it is advancing, slowly...
