It's like literacy or numeracy or basic understanding of science. You have a problem as a culture if it is culturally acceptable to say "I can't do math" or "I can't understand written language" or "I have no idea about the universe around me or how people go about understanding it" or "I can't read or write logical directions."
Do you expect everyone to be a best-selling novelist (or a writer that is enjoyed for all history?) No.
Do you expect everyone to be the next Ramanujan? No.
Do you expect everyone to be the next Knuth? No.
But it is expected that everyone have basic skills in these kinds of things. It's just necessary to understand the world. If you don't understand these kinds of things -- if you don't have basic skills in language or mathematics or logic -- then you are at a disadvantage in modern society.
I group computer science'logic here separate from Mathematics. Perhaps it shouldn't be. But having a population that doesn't understand things like this shuold be considered as problematic as a population that can not read and write.
