Why isn't nuclear power the answer to climate change and energy shortage?
Solar panels, batteries, and wind mills are comparatively easy to produce at ridiculous volumes. They’re a cheaper, faster and cleaner solution.
Buildings are also “adapted for each location”, but there is still an entire corpus of standardized techniques to do that that massively reduces costs compared to literally solving the problem from scratch at each site.
And why is it the case that “we don’t have the skilled people to do that”? If people value it, they’ll pay for it- and people can learn new skills in response to market need / pay - there is no predetermined number of “ad-tech software engineers” for example, they were “created” by the people themselves responding to market forces (pay)
Maybe you could have a universally implantable design, and maybe you could train people with the relevant skillset. The point is: we haven’t, and we aren’t, so other ways of generating green power are easier and cheaper. Nuclear will play a role for sure (the climate crisis is such that we need to do all the things) but it won’t cover more than 10% of our energy needs. I would be glad to get a rosier outlook on nuclear though.

The dream was "power too cheap to meter". Didn't come true back then, and it turns out after you account for safety systems like a containment building and backup cooling, it's far more expensive than alternatives.
To make things worse, making nuclear remotely profitable relies on running it as close to 24/7 as possible. Given that renewables exist and produce cheaper power, nuclear only gets to offer anything when renewables aren't working, which makes it even more expensive.
Economically, it's extremely risky. Why risk billions on a plant that might profit 20 years down the line, when you could build solar or wind faster, and profit faster?
Politically, it's not great because construction times are very long, so any politician that starts building them probably won't be there to see the benefit, and may have their work stopped by a successor.
Practically, we can't build it fast enough. It's a big, complex, specialized tasks that few people do because there's not much market.

Nuclear can be safe but look at the failures of the USSR on Chernobyl to see how it depends completely on a country's culture and willingness to pay for this safety. Or even Fukushima, in a country very risk-averse and rich, corners were still cut even with the responsible engineer calling out that the sea walls were too low.
Should we trust governments around the world that each single one of them will keep their nuclear power plants safe for the foreseeable future until we can move away from it (let's say 50-100 years)?
I'm on the camp that no, we can't.
Just look at China, with ~50 nuclear plants (just 5% of energy production), while they have thousands of coal plants. It's practically impossible that they can shift to a reusable carbon-neutral energy production methods.
Also, China can build a hundred coal plants in a year, but there's no way it can do that with nuclear.
The realistic picture is that growth cannot be sustained and there will be dire consequences due to other factors too.
(climate change, migration, wet bulb temperatures, crop failures, people being too good at capitalism, etc.)
Compared to all the construction China has done in the past 50 years, it doesn't seem that difficult a target.
> Also, China can build a hundred coal plants in a year, but there's no way it can do that with nuclear.
That isn't a law of nature. They can build hundreds of plants of any type in a year.
