Every once in a while, I see some posts based on maps and projections. And I cannot get it when adults still discuss these stuff. I had my first atlas when I was a 4th grader and the projections were depicted in detail in the first 15-20 pages. It is easy and foundational that I assumed everybody was aware of this information. Instead people rediscovered the Earth on each blog post mentioning the exact same thing. Amazing.
