caught the "decade" part... ;)
I suspect it will become a layer 2 solution for Steem (though it does not need one for scalability) and more importantly an excellent tool for interoperability and liquidity for SMTs. Steem Engine is on-boarding blockchain currencies build on EOS and plans to add ERC20s. I have no doubt they will add ERC721s, add Loom tokens, Cosmos coins and so on... Layer 2 market.
