For me, opposing experience and education is simply silly.
Probably more than 70% of all people would learn much faster on their own than at school. But, learn WHAT? :
1. Probably less than 1% would guess correctly what they SHOULD learn, and
2. in general they will not be able to assess their own knowledge...
Compared to an academic career, you'll have a more "real" goal of making
good software (instead of publishing papers). Also, this experience will
be much more relevant for your future job.
