Neither safe nor affordable are booleans. They are on a scale, and a dependency exists between them.
Anybody may have a different judgement with respect to exactly where on the scale is appropriate, but we cannot just pretend that there's no trade-off to be made. Or that absolute safety is even a possibility.
It's pretty freaking safe, isn't it? We've literally had zero-fatality years in the US. That doesn't happen through good luck alone. Clearly the manufacturers, regulators, and operators are doing almost everything right.
