What? I get that optimism feels nice, but... resources on Earth are limited, and we are starting to feel it (actually for conventional oil, the peak was in 2008, and Europe's economy has been feeling it since then). Extracting metals gets more and more expensive and harder.

Renewables are extremely far from looking like they could remotely replace fossil fuels, and given that building nuclear plants takes decades, it's starting to be short on that end too.

More fossil energy is definitely not good: it's killing us (literally), and it will get worse.

It's really not clear at all, today, that we will be able to replace fossil fuels entirely with renewable energy (meaning that we are likely to face a forced degrowth). And anyway, the more energy we have, the more we behave like humans, and that's killing the Earth's biodiversity (no need to go to Mars: we are changing Earth into something that may look like Mars eventually).

The best thing that could happen in 2023 would be to realize that less is more.

Fissionable resources are plentiful and we've barely started to extract them.

Sure, because our whole society depends on fossil fuels. We are not looking like we are even starting to move away from them, so probably we will have finished screwing up the climate before we run out of fossil fuels. At which point it will be too late for building nuclear plants anyway.

Now say we realize that today (which is very not clear) and start building nuclear plants: still it is absolutely not clear that we can remotely compensate our addiction to fossil fuels. In other words, it may well be that we need more nuclear plants in order to control the forced degrowth that's coming.

Actually, and if I understood correctly, most nuclear plants today use uranium 235. Which is limited. New generations use uranium 238 (which is much less limited), but they still need some uranium 235. So even there we need to transition sooner than later. And given how much f** we give about moving away from fossil fuels in order to survive on Earth, I wouldn't bet that we give a lot about transitioning to newer gen nuclear plants.
