I'm pushing 50 and I tend to think that there's maybe one or two generations left to live before society collapses due to this shit. The copium being taken by some people on where we're at is pretty nuts, not to mention the outlandish solutions people are proposing like putting reflective particles into the atmosphere to 'dim the sun', rather than just do the things scientists have been shouting for decades. I've done my part (which amounts to measurably nothing). But as you said, it's over kids. We're at the part of a roller coaster ride where the first couple cars have started down that hill and there's no way to stop the acceleration of everything else, only unlike the roller coaster, the bottom is the end of the ride.
