Human form robots are a case of Jake of all trades and master of none. Sure I have a dishwasher thats more efficient at doing the job than me but I still end up doing dishes because the cast iron frying pan can't going in there without ruining the polymerised layer of oils that have been baked into it and i would have to repeatedly oil and reheat it and stink up the house with smoke reseasoning it afterwards, and I have hand wash the thermos and travel mugs, and dishwasher arent good for the sharp knives and etcetera etc etc... sure the rumba can vacume very efficiently but it suck at gating around furniture leg or gaps to small for a 14'' diameter circle to fit through so I have to vacume all of the bits it can't get to. Sure the a robot lawn mower can do my yard very efficiently but it cant move the childrens toys out of the grass or open the gate to the front yard or close the gate to keep the dogs from running out the gate once its open. Specialized tools suck at edge cases. Human form robots if they ever works (big if) can do all of the edge cases and take advantage of all the tools made for humans I already have to do all of the those other jobs.
