By "stop at steel", I meant to ask how far their bootstrapping went — did they bootstrap from stone-age materials to just, say, pre-medieval steel metallurgy? Or did they go on ahead to technologies like organic polymers, machine tools, bicycles, internal-combustion engines, vacuum tubes, semiconductors, digital computers, and heavier-than-air flying machines?
I wonder if Ariel Salaverria sells his work at handicrafts markets here locally. Maybe I could go apprentice with him :)
