What did you notice?

You were watching for something: a slip, a hesitation, a response that felt too smooth. Something that didn't quite ring true.

But "ring true" is not a definition. It's a feeling. Passing the test doesn't prove a machine thinks. It proves it fooled someone. Those aren't the same thing.

A great actor can convince an audience they're devastated without feeling anything. ELIZA convinced people it understood them using nothing but : no learning, no inner life, just rules.

Did you notice how often ELIZA just repeated your words back? "Your boyfriend made you come here." "Your father." It rarely said anything new. It mirrored.

Here's how it worked: ELIZA scanned your message for certain words. If it found "mother", it asked about your family. If it found "I am", it reflected it back: "Why are you..."

No memory. Each response came from that single message alone, with no knowledge of what came before. It couldn't remember your name, your story, or anything you'd said. And yet people felt heard.

Turing never claimed the test would resolve this. Passing it doesn't prove understanding. It proves fooling. Turing wasn't claiming otherwise. He was saying it was a reasonable stand-in, given that we can't define the real thing. Today's AI works very differently from ELIZA, but whether it understands anything is a question we'll come back to.
