I want BTC to fulfill our need for global electronic cash and Ethereum to fulfill our need for a developer-friendly Dapp environment.

The bigger Bitcoin becomes, the more we all benefit from a stable universal currency. The bigger Ethereum becomes, the more we all benefit from a rich set of shared resources for developing apps that use BTC in ways that we've been dreaming of for years.

Bitcoin's killer apps might be Ethereum Dapps. That wouldn't mean that Ether "failed" as a currency or that Bitcoin "failed" because Ethereum was used to build the killer apps. It'd mean both are succeeding!

Life is more colorful when it's not just black and white.
