Wisdom is not a function of age. It's not a present you open on your birthday. You may get wiser as years go by, but that doesn't mean you get to be wiser than those around you. There are plenty of people who are wiser and more knowledgeable and insightful than those who were born earlier. There are also plenty of people that in spite of their age they attained very little wisdom to show for. The "ok boomer" meme originated in cases where this particular blend of people started to rant about younger people basing their attacks and criticisms exclusively on their age difference.

There’s another word for elder “wisdom” - superstition.

I question anything I’m told that doesn’t have proof attached, or singular experiences that are then extrapolated to cover an infinite future.

This always comes up in the same places: - Piss poor processes - Refusal to apply updates - Unverifiable decisions that exist for years

There’s a reason people say, “Ok boomer”.

There's good reasons alright. But as with everything humans adopt, it's also abused to oblivion in many situation where it doesn't even remotely apply.
