The Manhattan project employed some significant % of all of America. A project of that scale will likely never happen again.

It was also about far more than the science. It was about industrializing the entire production process and creating industrial capability that simply did not exist before.

My comment was not limited to the U.S. government.

And the Manhattan Project cost $30B in today’s money. Compared with some of the numbers Congress has allocated recently, I’d call that a bargain.

Does quantum computing need that though? We don't suddenly need a large, unique supply chain for these computers. We don't need to dig up the qubits and refine them. Testing doesn't blow up the computer.
