Money tends to flow to where it's fundamentally governed by physical laws and limited capital resources. All consumption is ultimately for time and energy - industries concentrate around energy sources like oil or computing, while individual consumption gravitates toward content that occupies significant time. All of these patterns can be understood through this framework.
The ultimate form of currency should approximate the right to consume energy or increase entropy. PoW was a good approach but failed because energy consumption occurred preemptively, and the Petro Dollar System was close but is being threatened by technological developments and various non-oil energy alternatives.
