Unpopular opinion: nobody in my group chat knows what the CAP theorem actually says, and I proved it last week
We had a 45 minute argument in our group chat about why a website went down during a storm, and 4 people kept saying "you can only pick two, it's the rules." I pulled up the old Brewer talk from 2000 where he says it's really about giving up consistency OR availability when a partition happens, not picking two of three like a menu, and two guys still said I was splitting hairs. So what's the dumbest thing you've seen someone repeat about a concept they never looked up?

Makes sense that two guys dug in even after you showed them the actual talk. People love the sound of a rule more than the rule itself. You see it everywhere, like how everyone says you have to drink 8 glasses of water a day or that we only use 10% of our brains. Somebody says it once, it sounds smart, and then it just gets passed around forever without anyone checking. The "pick two" version is catchy so it sticks, even though it's wrong. Most folks aren't repeating stuff to be jerks, they just never had a reason to look it up until you made them. And by then they'd rather argue than admit they had it wrong the whole time, which is its own thing.
