I remember a similar level of breathless excitement about fusion in the early '80s, and I'm sure there was breathless excitement before then.
Fusion as an everyday power source sidesteps a lot of issues that need to be overcome, not just the fact that no existing reactor produces a net gain. I think many current projects are looking into isotopes as fuel sources, which might prove viability but isn't exactly going to make limitless power for "virtuall free". Last I checked, deuterium and/or tritium weren't exactly just lying about in massive ready-to-use quantities. Then there's neutron emission/poisoning (I don't think aneutronic fusion is a property of using isotope fuels but I could be wrong), containment, cooling, etc. and I know I'm barely touching the surface.
I read a research paper (probably arXiv so YMMV) that I can't find at the moment where the researchers were convinced that fusion was a product of quantum tunneling, and not of massive amounts of pressure or energy being dumped in. I'm paraphrasing and also not a scientist so I might be mis-remembering or just plain wrong but the gist was that if, even with all of the energetic hydrogen in the sun's core, fusion only took place because of tunneling then hydrogen (non-isotopic) fusion as a real power source is fucked as a power source.
Solar and wind have definitely benefitted from continual investment and research over the past 20 years, and I think fission would as well (I can't think of a way that governing bodies can get together to figure out how to allow the secure development of modern breeders, but they would solve all but the actinide hole for nuclear waste).
If the fucktons of money and thought being spent on fusion were directed to solar, wind, and other renewables, as well as fission, the world as a whole would be better positioned to hold the line on climate change.
Of course, as long as people with clout continue to have a 10-20 year sense of responsibility, that's not going to happen, and 2100 is looking to be a shit year for humanity.
