I think folks are missing the forest for the trees: he's saying pick a language to really focus on and own it. That's your big tool now. Of course there will be other tools for more specific contexts. But having one big popular language in your tool belt (regardless of what it is) is better than skimming the surface of the tool-de-jour, especially as that tool is likely de jour because it satisfies an en-vogue concept.
