Yeah, I'm still stumped by the whole supply graph because everything requires tooling, and tooling required research, which required benchmarks, more tools, computers.. which required tooling .. so on and so forth. It's easy to forget how much time, effort and people are involved into anything, and all that had to be handled over economic and finance theories and logistics ... quite the madness.

And while we're at it.. I often look at insects the same way. That's a tiny ecofriendly, self reproducible (or almost), fault resistant, pretty smart nanotechnological robot.
