We’ve been having back to back “once in a lifetime” crisis since the early 2000s,
And people on the left has been predicting the collapse of capitalism since before WW1. Are you certain you are not making the same mistake they did by completely underestimating the liberal consensus' flexibility and resilience? Something, something, know your enemy... how does that line from Sun Tzu go again?
Anyway I don’t see any point in responding to nihilistic perspectives.
It is not nihilistic to turn away from magical thinking... especially if said magical thinking has delivered no tangible results for more than eight (that's 8) decades now and still counting.
If you believe that the libertarian left has no option but to tackle the future with the same woefully orthodox theory and consequently misguided praxis... well now that is what I would call nihilistic.
I mean... doesn't it ring any alarm bells for you that the two libertarian projects in recent history that anarchists got most excited about - Rojava and Chiappas - wasn't instigated by anarchists at all but by tankies that decided to dump Marxist-Leninist orthodoxy in the rubbish bin and go back to the drawing board?
Are you trying to tell me that anarchists cannot - or simply won't - do the same?
If they can't, they have nothing to offer the working class.
