It's a key example, and is the same failure mode nuclear power has.

Nuclear power could be engineered to be at least as safe as (most) commercial flight.

But it won't be - and this is absolutely predictable. Because of politics and money.

There is no answer to this, except to fix politics and money and make them as safe as commercial flight.

That's a whole different scale of problem to fixing climate change.

IMO this isn't a utopian fantasy, it's absolutely critical for species survival. But it doesn't look as if we're going to be starting the process any time soon.

Exporting the same problems to Mars or upload space or wherever won't solve them either.
