Proof of Work systems are outdated and will not scale well into the scarce future availability of electricity

With the rise in global warming and eventual premiums to keep using dirty energy, prices for electricity will most likely skyrocket in the coming decades, and with it, sustainability of Proof of Work chains.
For September 22, 2020
I Agree. PoS or like-systems will be the future.
Against September 22, 2020
While I agree that PoW has serious issues and limitations in terms of sustainability, it provides strong incentives to secure L1 and have been tested more heavily than PoS systems. I am not convinced that PoW will be completely replaced by PoS alone. Hybrid stacks are more likely

POW will stick around IMO
