Yeah, unfortunately, nuclear power should have been heavily invested in about... 50 years ago. The "The best time was yesterday, the second-best time is now" line doesn't apply with advancements in other energy sources and the sheer time it takes to build and get a nuclear plant operational. The best time was yesterday - now is perhaps the worst time.
Still, it is always good to push back on anti-nuclear sentiment. Every nuclear plant kept running is a massive amount of fossil fuels removed from power generation. I remember when Merkel closed a ton of nuclear plants in Germany for dogshit PR reasons, handing power back to fossil fuel suppliers.
