Also relevant given the post is also about fusion.

At this conference for progress nerds, with big arguments between solar and fission nuclear "no one wanted to defend fusion".

> Fusion promises cheap clean limitless power if only we can solve difficult technological hurdles. But we already know how to produce cheap clean limitless power. The only delay is regulatory, and fusion doesn’t solve this.

...

> the only pro-fusion sentiment I saw at the conference was a series of graphs comparing “fission” and “fusion” and showing strong performance advantages for ”fusion” in all categories. But it turned out the pro-solar faction had mischievously labeled solar as “fusion” since it ultimately comes from the sun’s solar core. It was a good trick - think of solar as a new high-tech wonder, instead of as the annoying thing environmentalists keep nagging us about, and it really does look like a miracle.
