Huge amounts of public and private funds have been funneled into the fusion race worldwide, with the aim of ultimately manufacturing fusion machinery that could bring electricity to the grid with no carbon footprint...

What are they building the research materials, equipment, etc out of??

Oh, and this means spend more money.

Remember we built the atomic bomb in a little under four years.

Nuclear fission is a lot easier than fusion. Heavy atomic isotopes want to split, it doesn’t take much to encourage them. Forcing two atomic nuclei to fuse is far more difficult.

That is both true and completely irrelevant.
