being a good engineer is also understanding when something is a waste of time because the gain is insignificant 99% of the time

Using "good engineering" as an argument against learning is definitely an interesting approach.

I think siblings point needs to be made more sharply: this could've gone somewhere good, "I evaluated it and found the gain was not worth the cost to change", but instead went to "the gain from a change is insignificant 99% of the time, so it's not worth understanding it".

The latter is poor engineering.

It seems like all of your comments are like this. Consider stopping that!
