Fairly modest tariffs and incentives would probably swing things. It needs to be planned ahead though as training and building factories takes a while. One reason China is strong now is they trained a load of engineers 20 or 30 years ago.

We can't change material cost at the moment, but this is something we could have influence over. Recycling steel and aluminum would be dirt cheap. We'd leap even farther ahead in training AI models. We'd reduce carbon emissions from shipping. So many beautiful outcomes.

I can dream. If there's one upside to the AI boom, I hope we see a plethora and overbuild of power infrastructure and a second coming of nuclear energy. Alas, both blue and red hate nuclear when both should love it.
