While node is doing the calculation, it won't be doing anything else (like serving the next request). If a more traditional server is doing the calculation, it will spin up another process to handle the next request.
If all you do is calculating Fibonacci, you can get ~(amount of CPUs) times the performance. You could use multinode for the same effect, but this is additional work.
In the end, it's a matter of the type of service you are doing. If it's a Fibonacci generator, you'd use something that's better suited than either node/JS or any other scripting language.
If you are doing something that's I/O heavy (which is probably the majority of today's web applications), node or other scripting languages might be better suited because they are easier to work with for most of us.
It's just tools. Not religion. I wouldn't use a hammer to remove a screw. And I definitely wouldn't write hateful articles (I'm referring to the original one) because somebody was using a screwdriver instead of a hammer to remove the screw.
It's a troll article, but I'd like to point out that the "UNIX way" is alive and well in node.js. I spawn new processes to do heavy lifting (e.g. thumbnailing, hashing files) all the time. I put jobs into queues in redis and handle them in other node processes. Obviously in co-operative multitasking it's wrong to block the rest of the server.
