how much technology requires bootstrapping (metallurgy is a great example of this)
I would love to see a reality TV show about a metallurgy expert making a knife or other metal tool from scratch. The expert would be provided food and shelter but would have no equipment or materials for making metal, and so would have to find and dig up the ore themselves, build their own oven, and whatever else you would have to do to make metal if you were transported to the stone age.
