Wisdom is very rare. I constantly have to tell people "we did it like that in 2012 because it seemed like a good idea and there were no better options - but this is 2026 and there are now better options and we shouldn't do things the old way instead.
Too often people get an idea and don't stop to ask if there is an even better idea. (I'm guilty of this myself). Often it takes a while to figure out what the good ideas are, but people want an answer now.
