Why do you look at it as a competition? The future of decentralized apps will be multi chain according to Ethereum's main website, that means they don't look at other smart contract platforms as competitors, maybe because one blockchain can't provide all of the three features that must be in a blockchain, which are security, scalability, and decentralization. All available blockchains provide only two of the three mentioned features. Therefore, we should look at its roles as complementary roles.
