Not sure about C developers, but there are plenty of developers in the
functional camp who still say OOP is bullsh*t :)

And many of the GC arguments were only invalidated 10 years after Java came
out, as multi-core became the norm and the GC could use a "free" core.

Seriously, what do JavaScript, Ruby, Python, Erlang and Scala have in
common? The only thing I can think of is "they're not Java" :)

I think Python is just as slow to evolve as Java, maybe even slower. And
it's not just the language itself, but the community as well: Python 3.0
came out in 2008, yet not everyone is on board just yet (
https://news.ycombinator.com/item?id=5009484).

Scala seems to be on the other end of the spectrum, adding a truck-load of
features every couple of years. My feeling is the Scala guys haven't
learned that every new feature starts at -100 points yet:
