“Goddamn it, do it yourself. You’re five hundred years old and you can’t use a telephone? Read the directions. What are you, an immortal idiot?”

Favoring life sentences without parole instead of capital punishment, as quoted in Time Magazine (2 June 1986)

he wouldn't have been able to tell him the ways the telephone would affect the world. He didn't know that people would use the telephone to call up and find out what movies were playing that night or to order some groceries or call a relative on the other side of the globe. But remember that first the public telegraph was inaugurated, in 1844. It was an amazing breakthrough in communications. You could actually send messages from New York to San Francisco in an afternoon. People talked about putting a telegraph on every desk in America to improve productivity. But it wouldn't have worked. It required that people learn this whole sequence of strange incantations, Morse code, dots and dashes, to use the telegraph. It took about 40 hours to learn. The majority of people would never learn how to use it. So, fortunately, in the 1870s, Bell filed the patents for the telephone. It performed basically the same function as the telegraph, but people already knew how to use it. Also, the neatest thing about it was that besides allowing you to communicate with just words, it allowed you to sing. … It allowed you to intone your words with meaning beyond the simple linguistics. And we're in the same situation today. Some people are saying that we ought to put an IBM PC on every desk in America to improve productivity. It won't work. The special incantations you have to learn this time are "slash q-zs" and things like that. The manual for WordStar, the most popular word-processing program, is 400 pages thick. To write a novel, you have to read a novel—one that reads like a mystery to most people. They're not going to learn slash q-z any more than they're going to learn Morse code. That is what Macintosh is all about. It's the first "telephone" of our industry. And, besides that, the neatest thing about it, to me, is that the Macintosh lets you sing the way the telephone did. You don't simply communicate words, you have special print styles and the ability to draw and add pictures to express yourself.
