I guess the point I'm trying to put forward is that we can't make those kinds of trade-offs and comparisons. Or, we can, but it's a fruitless exercise. We can't know how many things would be different, or how much better or worse circumstances would be with the removal of an event as significant and world-changing as WW1 / WW2 (the first affects the second significantly).

Maybe there would be a rise in anti-semitism elsewhere in say, the US, and it results in the death of millions more jewish, LGBT and black people than occurred under the Third Reich. Maybe The cold War turns hot and there's total nuclear destruction wiping out the entirety of human life.

Maybe things are great, Germany manages to pull itself out of the greatest economic depression ever and they become an agrarian society. Bruno Schulz survives, but his next book kind of blows.

There's no way we can say what would happen, nor is it possible to follow the butterfly effect and see what would happen if these events occur. instead we have NASA, founded with a group of people who weren't necessarily good people (indeed, Werner Von Braun is an incredibly problematic figure), but ended up doing a lot of great things and influencing the world in what I consider a pretty positive way.

but that's just, you know, my opinion, man.
