Global supply chains seem to be gradually breaking down due to a mix of politics, demographics, and armed conflicts. Everyone has become accustomed to the post-WWII system of global free trade but historically it is an aberration and everything will eventually revert to the mean. I wouldn't be surprised if China disintegrates into another civil war within the next few decades. We can't necessarily rely on foreign countries to make stuff for us anymore so if we want to have stuff we might have to make it ourselves.
