I'm not interested in a debate, just observing that people who say (correctly or incorrectly) the world is coming to an end don't believe it, because otherwise they'd stop bickering and do what needs to be done.
I think there’s an incorrect assumption in there, that the people blowing the whistle for the last 30 years have been the people calling the shots.
The world isn’t coming to an end but our cozy place in it might very well be.
Nuclear power should have been the only thing built by rich countries for the last 5 decades but of course there are real dangers regarding the unreliability of us humans as maintainers and operators.
The people calling the shots may believe that the costs of stopping climate change outweigh the benefits.
On the other hand, they may just think there is no political route to stopping it.
I have never been an advocate of nuclear power in general, and I don't think the world needs more conventional fission reactors. I don't believe fusion power will ever be viable either.
But my pop-sci understanding of a fast breeder reactor is it consumes waste and produces more fuel.
Couldn't it be ripe for someone to take up a similar role to SpaceX only with nuclear power? Assuming we do really believe that climate change has to be stopped at any cost.
