This implies that people stay defensive concerning concurrency ( like
me right now ) and do not embrace it like e.g. Erlang does. Sometimes
there is a radical change in the way we design applications and a
language is the appropriate medium to express it succinctly.
Concurrency is one example, writing GUIs and event driven programs in
a declarative style ( Flex, WPF, JavaFX ) is another one. In
particular the latter group shows that new skills are adopted rather

I don't see that a concurrency oriented language has really peaked
though yet.
