To be fair (and to make the opposite point of what I was making above)
I should describe a recent encounter with some C# folks.
They were doing something in what needed to be a fast loop.
Looking over the code I found some dictionary lookups.
I suggested digesting the dict-key into an int and using arrays instead of dicts.

They did it and got a 10x speedup.

So C# (just as your above cited typical Java programmers) certainly can produce
programmers who are clueless of what's 'under the hood'
