PoW sticks because as a consensus backbone because it's 1.) easy to understand and implement and 2.) it's guarantees distribution of updates to the distributed state. IMO there are better ways to trustlessly secure distributed state but like all things there's a trade-off. The dirty secret of blockchain tech is that it can't scale - not without supplementary protocols. Even when you get it to scale you still have to deal with the storage of the blockchain. Bandwidth constrains the size of the blocks, which in turn constrains the amount of transactions. Turn up the block creation frequency (a la ETH) and you solved one problemt (Tx throughput) but created another (chain size).

I am fundamentally opposed to PoW because it wastes so many resources, but, for now, it's the most viable way to secure a chain. PoS is doomed to centralization and relies too much on game theory and incentives for my tastes. just my 2 cents
