I think it's more about our resource growth outpacing our resource demand, because if that happens we bypass the resource competition that drives most conflict.

This has a lot of pathways, tech efficiency, slower population growth, more resource acquisition (asteroid mining etc). It's definitely possible in the large scope, but I suspect there will be periods of spiking demand that still cause lots of short term conflicts.

Famines and mass migration are very likely with climate change going the way it is. Over the course of 100 years I suspect the resource problem will alleviate but until then there will be a lot of conflict.

The only real long term trick is creating larger and larger gulfs between the resource demand and availability, buffers that can withstand the smaller scale changes. But, unfortunately, our current dominant systems of power view buffers like that as either weakness or opportunity that are antithetical to progress.
