I have a degree in engineering and suck at geography, math, chemistry, physics and probably many other things. Because i have other interests, like art or history. I maybe don't know where on a map are some countries, but i know all art movements from the 14th century onward and things about historical figures. Do you?
It's unfair to bash Lando for not knowing things, it's not like other people are knowledgeable in everything 🙄
For example, every math genius is a completely idiot when it comes to simple everyday stuff, because their whole life they focused on one thing that is interesting to them. It has nothing to do with intelligence or "ignorance".
And if you think knowledge=intelligence, then something is wrong with your intelligence....
