‘The Last People Who Know How It Works’: An Essay on AI and Losing Acquaintance With Machines

A short essay published on the engineering blog unix.foo argues that the most important thing we are losing as AI assistants absorb more of computing is not skill, but intimacy with machines. “The Last People Who Know How It Works,” published on June 26 by Cyrus Lopez, uses the friction of 1990s PC gaming to make its case.

The machine had terms

Lopez recalls a time when playing a computer game meant first understanding the computer: opening and reading files like autoexec.bat, sometimes building a boot disk for a single title — a floppy whose entire reason to exist was to start the machine in the configuration one program demanded. “A ten year old did this. I did this. You did it because you wanted to play badly enough, and the machine would not let you play until you had learned a little of how it worked.”

The same applied to hardware. The modem sang its negotiation out loud, and after enough repetitions you could hear when the argument was going south and the call was about to drop. You set jumpers on drives with a fingernail and knew which interrupt your sound card answered to, because guessing wrong meant it answered to nothing. “The machine was made of edges and you cut yourself on them, and that is how you found out where they were,” he writes.

Difficulty was the knowledge

The essay's central claim is that resistance was not an obstacle to understanding but the medium of it: “You only ever know the things that you can lose to.” Modern AI assistants, in this reading, are “the most accommodating thing anyone has ever built” — they never set terms, never make you read a config file, and rearrange themselves around your sentence. The consequence is blunt: “a machine that cannot challenge you is a thing you cannot know. You can only use it.”

Lopez explicitly rejects the standard lament about declining competence. The knowledge, he argues, has never been safer: the models have read every manual no human reads and will recite, flawlessly and forever, how machines work. What is dying is acquaintance — the plain intimacy of having fought a particular machine, lost, gone back, and finally felt the thing give.

More dependent, less acquainted

The essay ends on a personal note. Lopez went looking for a recording of a dial-up modem connecting — people keep such sounds “like pressed flowers” — and played it back on a modern computer that reproduced it instantly and perfectly. He knows that sound by heart, but nobody will know the machine that just played it, not the way he knew the machine that used to make it. The grief, he writes, is entirely ours: we are the last people who knew a machine by having it be difficult, and the last who will know that anything is gone.
