[Pyramus]

We didn't really learn (enough) - Fukushima made that very apparent. As an example, Angela Merkel, who used to be pro nuclear, changed position after the disaster.

The reason is that ever since Chernobyl there has been an active debate in Germany pro/contra nuclear (where in some parts there are still consumption limits on certain types of wild mushrooms and game due to contamination with caesium - 30 years later, 1000+ km away!). And the core argument pro was the same it is today: We learned from Chernobyl, nuclear reactors are way safer, Chernobyl will never happen again.

But if you followed Fukushima closely while it happened, the fact that Fukushima wasn't Chernobyl was sheer luck - had the wind blown southwards towards Tokyo (and not eastwards out to the sea like it did) Fukushima would have been worse.

I'm in no way saying that we have not advanced massively in science and technology - in fact, we have - I'm saying there are tricky biases at play here that make it very difficult to estimate whether we have learned enough.
