It could also be that he realizes that he is a PL snob/geek, and that makes him more likely to pick up and learn weirder/'more powerful' languages/paradigms. Other programmers (arguably most programmers) aren't PL geeks, not for a lack of ability, but for a lack of interest. Choosing to use more advanced languages may be great for him, but may just cramp the style of other people that aren't PL geeks.
