I agree that Ethereum has a strong future, but the implications of ideas behind this thread are long on more than just Ethereum. Issues of regulations, national borders, scalability, resilience, etc. will altogether lead to a diversity of blockchains, not a market completely dominated by one blockchain. Maybe Ethereum will be the leader and have 30% of the market (for example), so I'm not saying that the nature of industry in an economy will fundamentally change. But, Ethereum is not a fundamental set of truths, there are other ways to do similar things, and there are incentives to both create and use new blockchains. I'm long on Ethereum, NEO, Bancor, Cosmos, Polkadot...
