What's the purpose of doing anything? Why would we not want to improve on something we have chosen to do? If I choose to play chess but also choose not to improve at the game...am I not wasting my time? The less you know about this game the more you will loose at it...that does not sound like fun to me.
Leaning more of anything is a positive...not a negative.
