]]> JOBS: Computers are actually pretty simple. We’re sitting here on a bench in this cafe [for this part of the Interview]. Let’s assume that you understood only the most rudimentary of directions and you asked how to find the rest room. I would have to describe it to you in very specific and precise instructions. I might say, “Scoot sideways two meters off the bench. Stand erect. Lift left foot. Bend left knee until it is horizontal. Extend left foot and shift weight 300 centimeters forward …” and on and on. If you could interpret all those instructions 100 times faster than any other person in this cafe, you would appear to be a magician: You could run over and grab a milk shake and bring it back and set it on the table and snap your fingers, and I’d think you made the milk shake appear, because it was so fast relative to my perception. That’s exactly what a computer does. It takes these very, very simple-minded instructions—”Go fetch a number, add it to this number, put the result there, perceive if it’s greater than this other number”—but executes them at a rate of, let’s say, 1,000,000 per second. At 1,000,000 per second, the results appear to be magic. That’s a simple explanation, and the point is that people really don’t have to understand how computers work. Most people have no concept of how an automatic transmission works, yet they know how to drive a car. You don’t have to study physics to understand the laws of motion to drive a car, you may know the Windshield Replacement Cost but that doesn’t mean you have to know how to do the replacement, you can just play a company to get the service done. You don’t have to understand any of this stuff to use Macintosh—but you asked [laughs].

If you love Steve as much as we do you really need to read this interview from 1984 with Playboy magazine:
