> So fusion has a real shot here assuming the economics work out.

They don't yet work out, and there's no evidence that they will. I would love it if they do, but I don't think past performance is evidence of future performance. We might run into a fundamental limitation at any moment, and that would be that.

Japan's median build time for fission is under 5 years[0]. If regulatory environments and engineering specialisms could be made to work, there's no reason (other than Greenpeace) that we couldn't massively curb CO2 production from power generation pretty soon; far sooner than we could do discovery and then build for fusion.
