Computers may not have changed the look of the world too much, but they have had an extraordinary impact on the experience of being human. If people are now spending 50% of their time on screens, its in some sense equivalent to the world looking 50% different, right?
Not just in looks. Back in the 80s, we were happy when a car lasted beyond 100K miles.
Today, I'd be annoyed if my car needed anything beyond regular scheduled maintenance in that period. They're vastly more dependable, safer, better performing, and more comfortable.
