None of that material handling is cheap.

If exo-skeletons ever get good they should have a good decade long heydey just by virtue of not being regulated to high heaven (yet).

Basically the same reason knuckle booms took over from truck cranes for routine delivery.

None of it is handled directly by humans either. Exo skeletons would be sweet, I just think in reality construction is already highly optimized for regular strength humans. Would be very slim productivity gains.
