As far as I see it, AI is the reason they're unnecessarily paying 300k/year in the first place. A human engineer was the one that identified the problem with this JS dependency, and the human told then made AI fix its' original mistake.

That's a win for human engineers, not AI.

but they saved $500k. Before some humans knew about constraints in it. Now nobody knows.

Jokes aside, we will probably see everyone doing this, trying to remove human hands off of code, because they corrupt and AI does not.

Joke jokes aside why did we even code until AI?

If you start with something really really horrible, chances are even an accidental change by an intern can improve it.
