I think a better response to Ted's argument would have been to rewrite the fibonnaci number generator as a forked-off process with a callback that updates the requesting page on completion.

The thrust of Ted's argument (as I saw it, and completely agree with) is that telling people "inexperienced programmers can create high performance systems" is misleading or dangerous without pointing out that you can easily shoot yourself in the foot of you don't understand what is (and isn't) handled "magically" for you.

Using an algorithm that performs poorly in php or python isn't (necessarily) going to magically perform well in node.js's non blocking execution strategy. Abstracting away blocking network or io calls isn't going to help if you don't know (and notice) that your problem is the O(2^n) algorithm you're using.
