the machine does not have to be big... it can be a bunch of small spider like machines, or even more groups of machines: - material suppliers - welders - concrete ones (these can be essentially carrying tubes that are pump out concrete) this might be the next step for building multilevel farms, for agriculture (building huge pyramids). I've seen mockups/studies done in Japan (I think) that talk about exactly this, spider like swarms of robots moving along rail like structures maintaining/buidling fractal like pyramid structures that are super-tall ;)) the only way to take agriculture/housing to the next level... have multi-level cities (and not what pseudo-multilevel that we have now)... - rail constructors (rails for welders/material suppliers to move along)
