The counterpoint to this is that having a language that has a graceful slide between python like flexibility and hand optimized assembly is really useful. The thing I like most about Julia is it is very easy to both write fast somewhat sloppy code (e.g. for exploring new algorithms), but then you can go through and tune it easily for maximal performance and get as fast as anything out there.
