yes, governance is absolutely a sticking point. Even to your points relating to expertise is very much a consequence of governance, and past conditions dictating your available choices (in this case, a nuclear reactor isn't designed to be usable for all kinds of atomic power generation, their designs are always use-case specific. which is why the economies that committed to them using the technologies of post-ww2 cannot pivot so easily, as say China, who is still I think investing on scaling up thorium salt reactors -- I think, I'm not sure what's the state of the science right now.) Those current reactors are absolutely dirty, you will not find me disagreeing. Which is why I state specifically on the weaponisable part -- there's a political reason why nuclear energy sector threw its chips down almost immediately in the consumer market... because the waste is useable.

because the other problem with those economies, is because of their energy requirement, look at where they're pivoting: coal & gas. Nuclear (ideally) is still one of the cleanest options, if we can figure out how to utilize the developments in the last 30 years. BUT, at the same time, I would also argue with myself and agree with you that the urgency has been reduced, since renewable energy tech has really improved in leaps and bounds.

... except for one problem that's a genuine political and environmental concern - the rare earths and minerals needed to manufacture the photovoltaic cells, for example. the mining activity here has absolutely contributed to political instability and refugee crisis.

so to sum up, my arguments:

• no disagreements with the state of retail nuclear energy options
• no disagreements on the governance problem because retail options depend on tech that considers having nuclear waste to be a plus
• pointing out new scientific research is ongoing
• the issue with existing retail options is that they're very specific to the tech they're serving, so it cannot pivot
• this is where newly rich economies can lead the way e.g china
• shuttering nuclear reactors has actually caused an uptake in coal and gas-powered plants e.g Japan, Germany, I will have to look up Taiwan but I won't be surprised
• renewable energy much like most of computing tech, is also a contributing actor in a lot of political instability in the global south.
