Intelligence is knowing merit of the effort and having learned everything empirically. I think that has been lost a lot today, new generations want everything easily and effortlessly, and that tends to have loose and lazy citizens, who do not worry about studying because everything is already on the Internet.
I wonder what would happen if one day a debacle occurs in civilization and lose access to the Internet and technology, having to return to ancient methods? I am sure that the answer will be that we are full of useless who do not know how to do anything because they have no way to look for it online.
The funny fact is, its the ones that need the knowledge that look online for it, the ones who are lazy won't study books nor study online for it.
