By all means, such hysteria never works:
> This is why I’m a doomer. Because the world has already ended, and human nature prevents it from creating a better world. Now, I’m just waiting for the end while enjoying the time we have left, like someone watching their last sunset.
I think it really happens when the harms of not doing the thing actually start happening and the pain of not doing it now becomes greater than doing it now.
That would likely mean once we get powerful enough (which might be global climate change/industry) we'll have one that we can't 'fix' in time eventually.
