You may think that, but productivity is really about a smart person who knows their tools.

And, of course, at least they won't have do a rewrite when it becomes apparent that they have to scale big time.

This statement is false. If all else being equal the better tool you use the more productive you become. Take assembly for insance. You can know assembly arbitrarily well (and any assembly tools) you won't be faster with assembly than you are with java.

With Java EE being clearly the better tool compared to Python and Ruby.

Python is laughable. One word; GIL. Nuf said.

That statement is not backed by any facts by you so it is unacceptable.

Google for "GIL Python" and have a laugh (or cry). I think that's enough backing for my statement to begin with.

Java, and so Java EE is considerably faster than Python, each and every benchmark out there proves this. Often it's up to a hundred times faster.

Java has a much richer ecosystem than Python and even more so than Ruby. Java projects are also much easier to maintain and much easier to scale.

Enough backing? It's just the start of why Java EE is the better tool ;)
