Yes. And 60. And 70. And any other number. [EDIT to clarify] Just think about the new languages or paradigm we may have. I dream of the google glasses - what will we have then? So, my answer is yes - for both type A and B. And if you don't have time to understand the problem space of type B problems, maybe you should take more time to study them. Learning is fun. Autonomy? I already have lots of it - and we all do. Maybe running things could add some more. Never before in history creating value was so easy with so little capital. Mastery? I keep discovering new stuff and learning. The amount of knowledge you already master is not important - especially since memory is tricky and you will forget stuff. Being able to quickly take new stuff is important. Purpose? You make your own purposes. There is no bad or good - or sense. If you find some, there is some. That's my zen approach.
