And you think this will happen simultaneously, to everyone on the planet everywhere at the same time? Including all the remote uncontacted tribes, isolated island nations, the herders and farmers in various hinterlands, and so forth? And once everyone gets "deathlusted" they'll all just act like crazed zombies, murdering and murdering until there's just two left and then they strangle each other in the wreckage?

You're demonstrating another example of interpreting "the end of my personally familiar comfortable lifestyle" as "the end of the whole entire world, full stop, it's all over and gone."

I'm sure there were people during the Bronze Age Collapse who thought it was the end of the world. And for their definition of "the world", I guess it was. But humanity is so much larger than your little personally-familiar corner of the world.

Sorry to be blunt, but the less we know objectivity, the greater the % of the population who'll be destroyed by our ignoring/denying ( including mine: this is global viability, not ideological )

Bear in mind: extinction requires that the % needs to be exactly 100%. Exactly. 99% won't do it.
