These kind of "all the experts are retired" take are getting tiresome.

When you think about it, until recently there were no experts in stabilizing the electric grid on a continental scale using renewables, because it was literally never needed before! Didn't stop experts from sprouting out when it became necessary.

There were no experts in building continental scale EV charging frameworks, either, until we needed them, and then there were.

Same thing all over again.

What we can say about nuclear is that it's been continuously supplying a non-negligible part of Europe's energy need for generations, and there are people who've been maintaining that. That's more than what we can say about a lot of our industrial needs in 2025.
