The abomination that is capitalism today: A young chemical engineer figured out how to crack oil for ¼ the energy, but it was never implemented... because it would lower the profit margin. If you make it 4x as cheap, you have to sell 4x more to make the same profit.

Yes very true. And that is the drawback to the physical world. The digital world can advance much quicker . That is why a company like Amazon can hit profitability a lot quicker than a Tesla even though both are in the tech arena.

I think, in a couple decades, 3d printing will really alter the face of what is taking place. When most household products exist as a digital file that is downloaded and printed out, we will see manufacturing change completely.

This in addition to what you pointed out about food production being localized.
