Of course . . . you can also use a flat rock to hammer in nails when framing a house, but a framing hammer might be a better idea. Doesn't mean it can't be done, though, especially if you're really good with rocks and already have them lying around, whereas you'd have to go to the hardware store just to buy the framing hammer.

My point was not "language X can't do project type Y," but rather that the things that put a language in the sweet spot for certain types of projects kind of inevitably pull it out of the sweet spot for other types of projects. I.e. it really is always about trade-offs. Sometimes the mere fact that you know how to use a given language is enough of a win to outweigh any potential benefits of switching to another language.
