Claim of humanoid robots building New York City in five months draws a challenge

An X post by @DavidSHolz claims 10 million humanoid robots could supply enough labor to build New York City in five months. Ben Reinhardt disputes the case for using humanoid machines for that work, while Teortaxes predicts mass production. The quoted factory post describes 10 million Optimus units per year as a target, with initial production planned for 2027.
