The tech has changed,not humans. Back in the day, Romans were happily watching gladiators slaughtering each other and all they cared was 'bread and entertainment'. Obviously not everyone, some tried to invent things,do commerce,medicine and etc. Those were the curious ones. It was a small percentage then and it is a small percentage now. The majority are much simpler people. The internet is bursting at its seams with amounts of knowledge available one click away from potential users( yes,you may need to look deeper to find it) but majority don't need it,they want entertainment and they get it.
