Whole article resonates so thank you for putting that up. The word POLYMATH is a little clunky for non-native speakers. If you were to ask people in the streets the word GENERALIST is probably easier to understand. I experienced that with a lot of words that tend to describe a certain type/trend/box. I'm not advocating against the word just trying to raise awareness why there's people out there that would rather simply break it down to "Generalist" and Polymath will most likely be a niche word on a global scale.
