I haven't used Dart, but I have 15 years of experience with Python and 10 years with Go. Go absolutely solves many of Python's problems including performance, single-native-binary compilation, dependency management, a lackluster-at-best static typing system, and many others. If you're an experienced Python developer, then you're used to announcements that promise a lot and utterly fail to deliver (consider all of the different package management "solutions", alternative runtimes, etc), but Go really does what it says on the tin.
