Have you ever framed a wall, done drywall, ran wires and plumbing through stupid amounts of odd placed studs in uncomfortable positions, carefully lifted 20’ metal roofing up a ladder without bending it, had to make countless runs to Home Depot for fasteners or furring strips, installed a septic tank and got the entire leach field and main line with the correct amount of drop, cleared land for a foundation and said oh fuck where did this 20’ tall 100’ long 40’ wide pile dirt and brush come from and what on earth do I do with it, operated an excavator, ran a water well drilling rig, These are just the few I came up with in my waking state. Not trying to be a dick head. Each one of these sure you could build a robot for but it would be a whole factory. And machines are high maintenance don’t get me started.
