It takes these 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.

One of the failures of technology companies is that they build technologies thinking everything else will work out.

Bottom line is, I didn't return to Apple to make a fortune. I've been very lucky in my life and already have one. When I was 25, my net worth was $100 million or so.

When you start looking at a problem and it seems really simple, you don't really understand the complexity of the problem. Then you get into the problem, and you see that it's really complicated, and you come up with all these convoluted solutions. That's sort of the middle, and that's where most people stop...
