In my teenage years (not unlike many other teens) I actually thought that people were stupid. Eventually I realized they are just lazy or simply don't care much for the long term consequences if the system works for them. Obviously it's no wonder such behavior could be mistaken for stupidity.

A few days ago I was watching this video where the presenter actually had the gall to tell the viewers that they should keep their crypto wallet hardware and keys in a bank locker. Took me a while to calm down.
