I have some memories of myself somewhere in space-time getting excited and declaring that all prior disasters were in fact a “blessing in disguise” and without them I thought I would not have this-and-that. I also observed others declaring similar statements. In all those cases a parallel universe where the same and maybe some additional advances are attained without the same disasters – it’s just getting swept under the carpet. Perhaps because in some way it’s kind of depressing to think of and it may diminish the gratitude one is trying to express.
