I really like this. Suppose we were to accept the suggestion that perhaps linearly decaying code is better built, and more robust, than exponentially decaying code.

Would this give newbies a great new tool to answer their question of which framework or language to learn?

Rails or Django? Django lasts longer. Angular or React? VueJs just a trend?

You could answer all these questions with this kind of analysis.

If someone wants to make a genuine contribution, a blog post contrasting the various decays of Javascript frameworks would be a hit.
