Age is a factor. Young people whilst educated highly are still very naive when it comes to thinking through the implications of their actions, so they are easy to manipulate and have them produce some nefarious dual use tech.

In fact I would go so far to suggest that someone in their 40's has learnt enough about the ways of the world to know alot better the differences in the rights and wrongs of the world. In other words, you are set up to fail if you follow the traditional educational route.

However its also worth pointing out, the age old problem of spotting giftedness. Einstein was mediocre at school and during his early year's at Uni, in fact it wasnt until his 30's that he started to come up with decent theories, so alot of companies hinder their growth & innovation potential by recruiting youngsters fresh out of an educational establishment.
