Personally I don't see any competition. Ethereum and SteemEngine are so far from each other they serve entirely different purposes. If an app like cryptokitties can melt the Ethereum network it gives everyone else quite a bit to work with in terms of filling the gaps.

I agree with you. I was very interested to read about the cryptokitties situation and wondered how changing Ethereum from proof of Work to proof of stake would work out. I also agree that the lack of capacity on Ethereum means there is room in this niche for other projects. In some regards, one day in the future, Ethereum’s main role may one day be seen as a Proof of Concept, and other blockchains able to handle more transactions per second, at lower cost may be the main players.
