It will never collapse, just transform and adapt to both the changing climatic circumstances as well as the changing needs of the ruling class. Capitalism is not some special separate system, it is just a variation of the same parasitic exploitative socio-economic approach that emerged thousands of years ago and has spread throughout the whole world since. As such "capitalism" as a relatively new iteration of the same approach will not collapse, instead it will evolve into a more optimal parasitic system to reflect the times, more optimal for the ruling class that is. Thus "capitalism" can never collapse it can only be forcibly collapsed. Nature and the passage of time are not on our side, we absolutely have to take the situation and our future into our own hands.
