Perhaps you need to re-read my comment. I'm saying they were exceptionally knowledgeable about things in general (STEM stuff). And, I'm saying WE are clueless as to how they knew a lot of things, they probably knew a lot more than we have clues to know about - thus, clueless
I'm talking about people all over the globe, separated by time, I don't know what your deal is with acting like I'm a white person poo'ing on POC - or how any of the racial/nationality/etc stuff you wrote factors in at all. You're obviously easily triggered and/or need to work on reading comprehension
