Not very many people knew how.
And not very many people wanted to learn.
After all, in those days it meant listening to your stomach growl in computer seminars. Falling asleep over computer manuals. And staying awake nights to memorize commands so complicated you'd have to be a computer to understand them.
Then, on a particularly bright day in California, some particularly bright engineers had a brilliant idea: since computers are so smart, wouldn't it make sense to teach computers about people, instead of teaching people about computers?
So it was that those very engineers worked long days and late nights - teaching tiny silicon chips all about people. How they make mistakes and change their minds. How they label their file folders and save old telephone numbers. How they labor for their livelihoods. And doodle in their spare time.
For the first time in recorded computer history, hardware engineers actually talked to software engineers in a moderate tone of voice. And both became united by a common goal to build the most powerful, most transportable, most flexible, most versatile computer not-very-much-money could buy.
And when the engineers were finally finished, they introduced us to a personal computer so personable it can practically shake hands.
And so easy to use, most people already know how.
They didn't call it the QZ190, or the Zpchip 5000.
They called it Macintosh.
Actually, while 1984 wasn't like Orwell's '1984' I sometimes think the present day is rather.
