towers of nano assemblers

I'm more and more convinced that to get a lot of that nano stuff to work, we need to be making towers of nano assemblers like you would make a tower of meta-circular interpeters.

The bug is in the bootstraping.

But I suppose we do it the hard way, by hand, as we did with meta-circular interpeters... then we can just keep on a building.

worked for some amino acids, why not other nano scale stuff?

Update:
The kicker is that we would be just part of the tower of nano assemblers!
