However I do think we can do better than proof of work. I think proof of stake can actually be much more secure while at the same time expending far less energy if designed properly. Granted, I haven't seen any pos protocol that has been designed properly. I have done some work to that effect tho: https://github.com/fresheneesz/ValidatedProofOfStake
