Complex societies definitely will survive. Probably, not the same societies that we have today, but I see no problem with that.

Bold claim withno real backing. This mass extinction might be the great filter. Seeing people dismiss it so flippantly and arrogantly is astounding .

I think we should make a distinction between optimism and blind fools. One is at least trying to find a silver lining. The other is just ignorance and arrogance .

That's a good point but I often can't tell the difference.

Plus... the optimists have been correct... at least, in every generation previous to ours.
