>>211791594>what will they use iron for that makes up for the process of making it vs just using whatever they do today?Iron is just a straight upgrade from stone dude there's no cost-benefit analysis required. Having sharper stronger more durable tools helps you survive longer.
I think your point was that they can already live long comfortable lives with the tools they have, but that's not really how humans work. Inventors and engineers, for most of human history, were aristocrats who could have lived off their estates. Fourier didn't need to discover wave analysis.
