The reason was that they always realized that "today's child is the father of the future."
Are you concerned that the future "generation" of Bitcoiners will be less knowledgeable about Bitcoin? I think it's not a problem, as more people come to crypto, there will be more people who understand only very little about. It's like with any other invention - first come the enthusiasts, then the masses who only interact with the surface. Early Internet was full of geeks, programmers, hackers, now people who can only visit Facebook and check emails are still using the Internet on a daily basis. Similar thing will happen with crypto - some people will only interact with it through exchanges without ever installing wallets.
