...how wonderful fusion energy will be, along with insights into the physics of fusion, there is no evidence that even if fusion reactors are built, that they will be affordable, reliable, or sustainable.

Besides the material science implications of handling neutrons at 14 MeV, a factor of 10 higher than fission neutrons, there isn't enough tritium on this planet as of 2025 to run a fusion reactor at 1000 MWe for a year.

I'm unimpressed with the handwaving about lithium metal blankets to breed tritium. I may be naive but somehow I have a feeling that lithium gas/plasma will mess with the stability of the magnetic confinement field.

Fusion reactors, even if they were made workable, will be too late to address extreme global heating because it is already "too late." Extreme global heating is here and fusion reactors aren't.
