What is it with people missing the point so many times in a row? Hence why I said "learn how you can use languages together and for the right purpose"—but I don't believe it should be the primary focus.
When you buy a drill, the main purpose is to make holes in things. When you buy a nailgun, the main purpose is to stick things together. One might do it better, one might do it faster, and yes, it's useful to know those things. But you're still building a house, not an opinion about a drill or a nailgun.
Ever notice how professionals treat their tools, versus amateurs? Photographers are a great example. Amateur photographers are all about cameras and lenses and tools. They buy gear like there was no tomorrow, and they do very little actual photography. Some of them make it past this phase and change their focus to what photography is really about (light, subject, timing) but most don't.
Professional photographers buy cameras for one purpose: because they get the shot. They buy lenses for one purpose: because they get the shot. And they buy everything else they need for one purpose: because it gets the shot. Their focus is the photograph and everything else follows. Of course there is some thought of what lens is right for what job, and what camera works best for what needs, and durability and portability especially; but mostly they use what works because they know it well and it gets the shot. And some pros use the most ridiculous gear that you'd never expect because it works so well for their particular goals.
There was an article a while back about a Iraq war journalist who used only Olympus 6MP zoom cameras made 5-6 years ago because they were workhorses, extremely portable, and held up to desert conditions. Non-pros probably thought he was crazy and dumb, but he got the shots. He shipped. You have seen his photos in the news, guaranteed. Talking about that gear out of context, it would make zero sense. But for the situation, it was perfect, because he focused on the task and not the gear.
I'm not scolding anyone, I'm not criticizing a choice of language; I'm saying, focus on the right part of your task. The tool is important, but the task is more important. That's exactly what the original article was saying, too, if you'll kindly go back and take note.
