"Jack of all trades, master of none" -Humanoid Robots

DISCLAIMER: I have nothing against general-purpose technology, it's great to have a machine that can do many tasks, but it's also important that it can do those tasks better and cost-effectively than special-purpose machines. I always hear the argument that humanoid robots are the future because they're generalists and their humanoid form means they can do whatever humans were doing. And while that is theoretically true, it misses an important point: Generality is only good if it performs better and cost-effectively than the specialist machines in those tasks.
