Learn to read... sure, I've heard the US adult population is 30% functionally illiterate.
Learn math... sure, I've heard the US has some of the worst math scores in the developed world. Learn advanced mathematics, why not?
Learn to rebuild your car's engine... sure, I'd guess that upwards of 95% of car owners don't know how to rebuild their engine! The shame!
et cetera et cetera et cetera... learn what you want, please don't tell me what I should spend my time learning, or what would be good for me to learn. Maybe those 30% of illiterate adults who couldn't be bothered to learn basic math skills will make great coders, but I somehow doubt it.
