If you read the book Black Swan, it is exactly one of its defining characteristics that it is unpredictable. The only thing you can do against black swans is making systems less fragile.
Small nitpick: Unpredictable for the observer. So in a way this pandemic was a black swan for some (naive) people.
On the other hand, I think it's good that someone like Taleb now goes around and pokes all the policymakers and governments that nothing of this was unpredictable and Corona is a white swan event.
Itβs been a while I read it, but you are right. Personally I think it already ranks amongst the most important books of the 21st century. Everyone should read it.
