I can accept being wrong about many of my opinions, but the exception is nuclear power.

I firmly believe that we either grow up as a species and embrace it as a pathway to fusion, or we collapse into resource wars and cease to exist as a species.

Nothing matches it in energy density.

@dave This is one you're wrong on. There is no way nuclear of any sort is ever practical in a world without centralized power backed by threat of violence. We can easily meet everybody's actual needs (not their technofuturist technofascist fantasies) with solar alone, even moreso solar and wind, and do this with local production where it's going to be used, no centralized targets that need to be protected.
@dave Capitalism and fascism by nature expand to consume all resources to preserve scarcity. Vastly increasing the available supply of energy doesn't fix that. See: proof-of-work and now "AI". Wastes that were funded precisely to soak up the supply.
