But you have to make a call at what point you stop trying to understand everything about everything. Thomas Young, the early 19th Century scientist has been famously described as "The Last Man Who Knew Everything" - the sum of human knowledge moves on so vastly that it is simply physically impossible to have an in-depth knowledge of every possible subject.
I don't think he's saying that he knows absolutely nothing about these subject (I'm sure he's probably got a rough idea that the oil probably came in a big oil tanker for example).
But there's over 5 billion articles on Wikipedia, and at some point you've got to decide that you haven't got time to understand how the Four Hu (to take the first random topic I found) came about because you're spending time thinking about how AI works or whatever.
