“Often people, especially computer engineers, focus on the machines. They think, "By doing this, the machine will run faster. By doing this, the machine will run more effectively. By doing this, the machine will something something something." They are focusing on machines. But in fact we need to focus on humans, on how humans care about doing programming or operating the application of the machines. We are the masters. They are the slaves.”

Context: A man’ s at odds to know his mind cause his mind is aught he has to know it with. He can know his heart, but he dont want to. Rightly so. Best not to look in there. It aint the heart of a creature that is bound in the way that God has set for it. You can find meanness in the least of creatures, but when God made man the devil was at his elbow. A creature that can do anything. Make a machine. And a machine to make the machine. And evil that can run itself a thousand years, no need to tend it.

Silence is a Commons (1982)
Context: Machines which ape people are tending to encroach on every aspect of people's lives, and that such machines force people to behave like machines. The new electronic devices do indeed have the power to force people to "communicate" with them and with each other on the terms of the machine. Whatever structurally does not fit the logic of machines is effectively filtered from a culture dominated by their use.
The machine-like behaviour of people chained to electronics constitutes a degradation of their well-being and of their dignity which, for most people in the long run, becomes intolerable. Observations of the sickening effect of programmed environments show that people in them become indolent, impotent, narcissistic and apolitical. The political process breaks down, because people cease to be able to govern themselves; they demand to be managed.
“The one job that machines cannot do is be a cruel plutocrat. That’s why humans are still needed.”
