Listening to Google I/O it seems that Dart will be presented to a standardization board after which efforts will be made to embed the Dart VM into Chrome. At this point I’m very interested in what other browser makers will think of Dart and if they will follow suit. Overall, I just hope that this does not create strife within the web community. Right now we all back a single language which allows us to focus more on tools and libraries to help us develop web applications with the introduction of Dart this could change the focus of many people, thus weakening many projects.
