What Can We Learn from the Computers of 1966? (harvardmagazine.com)

Harry R. Lewis has been a Harvard CS professor — teaching both Bill Gates and Mark Zuckerberg — and the dean of Harvard college. Born in 1947, Lewis remembers flipping the 18 toggle switches on Harvard’s PDP-4 back in 1966 — up (“click!”) or down (“CLACK”). And he thinks there’s a lesson for today from a time when “Computers were experienced as physical things.”
[T]he machine had a personality because it had a body you could feel and listen to. You could tell whether it was running smoothly by the way it sounded…
Unlike the unreliable mechanical contraptions of yore, today’s computers — uninteresting though they may be to look at if you can find them at all — mostly don’t break down, so we have fewer reasons to remember their physicality. Does it matter that the line between humans and the machines we have created has so blurred? Of course it does. We have known for a long time that we would eventually lose the calculation game to our creations; it has happened. We are likely to lose Turing’s “Imitation Game” too, in which a computer program, communicating with a human via typed text, tries to fool the user into confusing it with a human at another keyboard. (ChatGPT and its ilk are disturbingly convincing conversationalists already.)
Our challenge, in the presence of ubiquitous, invisible, superior intelligent agents, will be to make sure that we, and our heirs and successors, remember what makes us human… All computers can do is pretend to be human. They can be, in the language of the late philosopher Daniel Dennett ’63, counterfeit humans… The first error is suggesting that computers can be digitally trained to be superior versions of human intellects. And the second is inferring that human judgment will not be needed once computers get smart enough…
[N]o AI system can be divorced from the judgments of the humans who created it… Only hubristic humans could think that their counterfeits might completely substitute for human companionship, wisdom, curiosity, and judgment.â
Even back in 1966, Lewis says he learned two lessons that “have stood the test of time. Be careful what you ask them for. And it can be hard to tell what they are doing.”
One example? “In those pre-miniaturization days, the ordinary operation of the central processor generated so much radiation that you would put a transistor radio on the console and tune it in between AM stations. From the other side of the room, the tone of the static indicated whether the machine had crashed or not.”
Remember, even if you win the rat race — you’re still a rat.
Working…
