I've learned to not bet against the ingenuity of Google engineers, particularly those building web browsers and development tools. :) Given that they've added very basic support for editing to Developer Tools in Chrome already, once Dart lands in Chrome, I could see a push to make Chrome the editor-of-choice for Dart, if not web-based editors in general. And it's true, there's more to development than type-and-run interactive shells, but that sure makes web development easier, doesn't it? asm.js benefits Dart as well, since they can target the same approaches for their JS target code gen. The real question is when will Google add development alternatives to Android? Chrome's nice, but it takes a mobile platform to sustain an ecosystem of client-side developers these days. Perhaps Chrome-on-Android will eventually become the new PhoneGap?
