I'm sure other languages have the same problems too, like features getting added to the language which makes it harder to understand, leading to subtle bugs. I'm not a grumpy old saying that the old times where better, there are plenty of old JavaScript features that I also don't use unless I'm working with someone that is so in love with those features that they can't live without them, I just inform them of the implications so at least they are aware of the warts. The problem is when you are in love/hyped you easily neglect the ugly parts, and can tolerate a lot of pain. And then there's the curse of knowledge that once you learn something it becomes apparent/obvious.
