First, there are no CW requirements in the USA anymore. So all the arguing about it is mute. Up-grading, if you want the additional privileges then do so. If you don't care about them, then don't. When I first started you had to know CW at one of three 'levels', 5WPM, 13WPM, and 20WPM. So I learned it. I found that after a while, it was fun. You can carry on a conversation almost like on voice. Lots of special 'words', like E-S for 'and', etc. CW is a learned ability, it takes time to learn it, then build speed. Just like driving a car, it takes a while to be good at it. I don't see any particular need for having it to qualify for a ham license, but just 'cuz it's old doesn't mean there isn't a lot of it still around, and still useful. Would you rather have to learn ASCCII characters? It's used a bunch. Oh well...
