Should genetic engineering on humans ever become feasible to the point where you can make large changes to the body plan, I wonder if reverting bipedalism would be easier than fixing all of the problems it causes (such as, I assume, knees, due to taking all of the load on half of the limb joints, but, also, back problems, etc). With human computer interaction technology advancements, we may eventually move beyond needing hands at all, anyway.
