I think it is interesting to reflect on the idea that high technology builds on top of primitive technology. Just as he uses past tools to make more complex tools, every human era of technology builds upon the last. You could say primitive stone tools are in the recipe for developing an ICBM or a semiconductor if you go back far enough.

I think that's actually meant to be an orbital nuclear launcher, making the comparison even more appropriate.
