I don't necessarily agree with the author. I'm not sure about anyone else here, but after I learned a couple languages each additional language was "that" much easier to learn. While the syntax and general structure may vary from one to the next, the overall thought process is relatively the same. In my opinion (and experience), a 60 year old with 30 years of programming experience across various languages would probably be a better programmer than a 27 year old of equal competence who only has, say, 5 years of professional experience. Just because you're using a new language doesn't mean you can't draw from previous experiences. The same could be said for architects, animators or graphics designers. New software is constantly coming out but the style you've developed over the years is what can make or break you. Of course this isn't a perfect comparison to programming, but it's still a new set of tools to learn.
