We've been having back to back "once in a lifetime" crisis since the early 2000s, if you don't think a collapse is coming I don't know what to tell you. I see the system on its death-throes and the collapse of the AI-bubble might just be the thing that finally pops the everything bubble.
Anyway I don't see any point in responding to nihilistic perspectives. I think organizing in non-hierarchical ways improves the lives of people who practice them in the here and now and have revolutionary potential. If you think nothing we do has a chance to succeed and the system won't collapse, even with a looming climate apocalypse, I don't know what's there's to discuss. Go ride off into the sunset or some shit.
