Look at the boom of nuclear in the 70s. The industry wide and deep expertise from production, to planning, to logistics. Particularly the french did this par excellence. But nuclear has first languished and is now almost non-existent in Europe.

Contrary to capitalist believe you cannot solve all issues fast by throwing unreasonable amounts of money at it. You must built industries that synergies with each other, have deep institutional knowledge and capable workers that can deliver the tiny tolerances required to make nuclear safe and effective.

We simply do not have the (intellectual) capacity for this anymore and the effort is better spent on battery technology if Europe actually wants to have any stake in future of EV and renewables. It is significantly less capital intense too.

Plenty of comments here are disproving that baseless argument.
