In the post, the author makes an analogy of using PHP + MySQL as the equivalent of using BASIC, and then uses a quote that claims BASIC "has become the leading cause of brain-damage in proto-hackers."
I'm sorry, but using a language doesn't cause brain damage. And there are many levels to programming. And using Python, Ruby, C, C++, Java, etc., does not automatically make you a better programmer than those using one of "those other languages". You can write crap code in any language. You can also write great code in just about any language.
Matthew also mentions a real truth behind programming, no matter who you are - that it takes practice, lots and lots of practice. That's what it is - constant practice so you know better how to combat the troubles you might find the next time they rear their ugly head.
