>we can scale this up exponentially
Lost me here. It usually means something will require exponentially more resources, and eventually a finite limit (money, time, raw materials, land, energy, lifespan, speed of light, etc) will be hit.

That doesn't mean were going to go right to Dyson spheres so that every possible molecule is going towards scaling.
