Julia is simply a _much_ nicer to write lang than Python, it is more functional and it provides the user with far more ways to be expressive. I think the JIT warmup is less of an issue than its overall memory use but I can see that the former is more apparent to the average user sitting at their terminal.

I wish we would see a larger fraction of the energy invested into propagating the 'Pythonic' approach were _properly_ redirected into improving relevant aspects of Julia.
