That really, really depends on what the language is being used for. There are a lot of desirable qualities and features, and no single language has even close to all of them. With the vast, vast number of different programming paradigms that are effective for solving different problems, as well the various resource constraints of different computing platforms, a certain degree of "polyglotism" is absolutely necessary to be an effective, productive programmer. There's nothing "hipster" about it.
Now that I reread, I see that your comment was less a recommendation for Fortran-using Jeff Sagarin as it was a so-what digression. I took the bait, mea culpa.
