> And it’s fundamentally easier to make solar roofing safer than it is to make nuclear reactions safer.

I do not agree with this statement. Although I'm still thinking on how to prove this one way or another.

The closest analogy I can think of is between driving vs flying. It's easy to intuit that driving is fundamentally easier to be made safer than making flying safer. This is empirically not true.

Every rooftop is somewhat different. You can't just make all roofs safe.

While with nuclear reactors, you can design them to be as safe as needed. (Altough, I do think they are overregulated in certain areas.)

You should expect just the opposite. It’s totally plausible could make nuclear reactions fail safe if you do it right, and I think they’ve figured that out (supposedly). But there’s no way you can force thousands of different people to get up on a roof safely.
