The ironic thing is, as technology advances, people's mental skills decline.
People used to find their destination by navigating. Then they invented paper maps, so now we had a printed guide that we could use to help find our way. Then they invented GPS, and now a computer does all the "thinking" for us and tells us what to do. So now we tend to rely on a machine to do our thinking for us, and many people probably couldn't find their way to the next town without GPS to tell them where to go.
People used to do arithmetic. We used to know how to multiply and divide, using only a pencil and paper. Then calculators came along, and I would be willing to bet that today, a huge chunk of the population could not divide 956 by 14 without using a calculator to do it for them.
People used to read. Now we have audio books that "read" to us.
For every technological step forward, the teeming masses take an intellectual step backward.
