Yup. If everyone had made 5x the investment in nuclear 10-15 years ago (which would have made nuclear cheaper per plant as well: a huge part of the massive costs and time overruns on plants is the fact that they're pretty much one-offs), we'd be in a much better place with regards to the climate, and it would have very likely been worth the super -high costs (though questionable if we'd had also 5x the number of nuclear disasters). But we'd still be having the huge shift to renewables we're having now, maybe just a little slower.
