Exactly! We've been told by security forces that it is difficult to monitor the communication of ISIS members because of the channels they're using, so we need people who will think outside of the box to access those channels. That very well might be Anonymous. They've certainly proven they are capable of accessing secure information and causing disruption where they've wanted in the past.
I don't think you should write them off because some may be young or 'living in their parent's basement'. It really doesn't matter. Some of these people are dedicated, very intelligent and innovative. They can gain an exceptional level of knowledge very young.
I have a friend like this from school. At 11 or 12 he hacked the school network and stopped anyone logging in and using any of the computers (not just students, the admin couldn't access student records or anything). He was told off by the police and the school had to get experts to sort out the mess he'd made. He was told he'd get expelled if he went within so many feet of a computer again.
He ended up hacking the school payment system and removed the IT staff's salary from being paid, they didn't realize until after he should have been paid and it caused so much trouble for him. He did loads of things to taunt them, most of the time they couldn't prove it was him. He ended up getting expelled, but now works as a professional penetrator (he is a consultant and his job is to try to hack systems to see how vulnerable they are, then he finds ways to fix them). He earns so much money. He just loves the challenge.
Sorry for the long post, I just wanted to share how some very young people (even 15+ years ago) can know a huge amount and know what professionals just don't learn formally.
