The problem with tomorrow is sunk costs. There are many places I wish we had made a difference decision in the past - but we need to balance that with cost to make changes when what we have works okay.

There's also a recency bias, where you ignore how valuable some decision was in the past and ignore the fact that you maybe wouldn't even get to the place you are if "you made a different decision in the past".
I can't count how many times I've said "this is really bad, I it is worth rewriting to fix all the issues", only to discover that there were good reasons for all the past decisions and so we end up with the same mess as before - except that now I know what it must be that way.
Not always, but very often people in the past had good reason for what they did.
Those are the comments that should persist in the code. I hate when the AI edits and removes my "why" comments. I want the refactor to make it less messy but keep why it's that kind of mess.
