This is one of the stupidest articles I've ever read. Any half decent programmer, regardless of his experience level (just graduated from college to veteran 60 year old) can learn and be effective in programming a completely new language in one week (please note that when I say completely new I mean within the family of c-like languages). After one month, he'll have most of the libraries memorized.

This author seems to believe that experience in programming essentially boils down to experience in a language. That a 10 year veteran java programmer will have to start over from scratch if they switch to programming in c#. Totally untrue. Experience in programming makes you better at design, project planning, professional relationships, and project delivery. None of these have anything to do with what language you use.

Perhaps what he's trying to say is that if you are a terrible programmer with very low intelligence, your experience won't get you very far. And with that I agree. This author has done little but show he has low skill in the field, so it's unsurprising he finds his work to be below par.
