I answered one question 13 years ago where I still gets points for. Computing as a whole isn't so much in constant flux, it is only JavaScript that changes so much. Hell, I learned to use Apache 30 years ago, and I didn't need to learn anything new the last 25 years of that.

The change to Python 3 effectively either invalidated or deprecated tons of Python questions, or else required new answers to be written. In many cases we ended up with an annoying pair of popular questions to capture major 2->3 differences, because you'd get clueless users who thought they were running a 2.x interpreter but were actually running a 3.x interpreter, and also the other way around.
