The sensing part is really really hard.

Hands, mechanically are fairly simple to mimic, touch? the way skin feels micron-level shifts and subtle temperature changes is plain tough.

I can assure you they are not.

Human hands have absolutely crazy performance. Human hands have 15+ degrees of freedom. Sub-millimeter precision, no backlash. Strong enough to lift 100 lbs. Gentle enough to catch a thrown egg without breaking it. Rigid enough to hammer a nail without dropping the hammer. A compact forearm for reaching into tight spaces. Water- and dust-proof. Oh, and it'll last for decades without maintenance.

Even a $100k robot hand like a Shadow Hand can't compare.
