Specialized machines can, but it's amazing how configurable an arm with 5 2- or 3-jointed fingers can be. Without us even being able to change the fingers! I sure wouldn't complain if I could simply unscrew a hand to swap betweeen fleshy test probes, 1mm probes and grippers for fine detail, a variety of rotary tool attachments, etc. Or an arm to swap between different ranges of force; sometimes a gentle embrace is more appropriate than the sort of construction appendage that would break down a concrete wall and idly toss its pieces into a waiting truck over a lunch break. I guess what we'll really need are spine implants...
