This is total disregard for that the rest of the world considers valuable to them.

Yes and no. Where it's true, sure, arrogant jerks.

But the Lisp weenies have realized they know something the rest of the world doesn't. They think it's important, and it is in a sense. If only you knew that... you'd agree. (Ok, try not to take that too seriously.)

Unlike the impossibly abstract Lisp Truth™, this Erlang bit is centered in a very concrete fact that affects all of us. If you don't care about it today, it will affect you tomorrow all the same. You might as well argue that you never much cared for oxygen and who cares if the atmosphere is slowly turning to methane?

Joe wasn't saying you have to write Erlang, he was saying you need to write concurrent programs. If another language eats his lunch, it will probably do it in the same way that would be done in Erlang. There are alternatives, but the actor model is by far the most programmer-friendly that I have ever seen.
