|The stupid question is the question not asked|
Iím sorry if that was too Internetese. The joke is -> Q: Why? A: Because
You are completely right that itís all just a collection of tools and some have more complete libraries for a given task than others. What follows is nothing but
PHP is fine as long as I donít accidentally fall in one its manifold sink holes.
I could learn to enjoy Python and restrain my design instincts enough to not flinch when I have to look at it.
I could learn to love Ruby and forgive it for some of its troubling side cars.
I could be intimidated enough by Lisp to get good at it in defense of my own IQ and self-esteem.
I would rather work retail during the holidays than work with Java full time. I realize it has the best libraries for quite a few things and I use some of them. I would rather rewrite or port any given library from scratch than be stuck using it as anything other than a black box.
You got good real advice from others though. :P
