How do hammers feel about being pounded against nails all day? They don't feel it, it doesn't matter. It seems to be based on some of the authors emotions which I won't get into. If you don't like a language, don't use it. If something is making you sad or angry, you're dong it wrong. To put it simply: there is a reason javascript is gaining popularity. People who use it for things it wasn't originally meant for are pushing it into being meant for such things. Some of my reasons for js'ing is the simplicity of the scope, it's dual purpose frontend/backend, classless definitions, and I frankly like it and am productive in it. If you're more productive in a different language, use it. I received a lot of flame when i started my current position. Now we use js for most projects. Why? I was getting stuff done efficiently, and they noticed the benefits of node for straightforward solutions. It's also more readable when you do it well, especially when using coffeescript. Callbacks can be managed and should be.
Bottom line: If this language is a fad, or if using the language makes people fail, then those people will starve, and survival of the fittest will mean a different language wins. So, you don't have to fight it, because if it is truly worse, it will fail on it's own. Either way, fighting it will be in vain. Bear peace.
