The main argument builds on the assumption that the economy is a zero sum game when it clearly is not. Just because we invest these ressources in AI does not mean we could mobilize the same capital for other pursuits.
Precisely AI is being built out today because the value returned is expected to be massive. I would argue this value will be far bigger than railroads ever could be.
Overspending will happen, for sure, in certain geographies or for specialty hardware, maybe even capacity will outpace demand for a while, but I don’t think the author makes a good case that we are there yet.
