Turing didn't answer the question he asked. He reframed it, made it testable, pushed it into the open. Then left it there.
Three quarters of a century later, we have machines that write, diagnose, translate, compose. They hold conversations that fool people routinely. By almost any external measure, they perform.
We still don't know what thinking is.
That's not a failure. It is what this question has always looked like: not a gap waiting to be filled, but a question that keeps sharpening the closer you get to it. When a language model feels convincing and you feel that familiar hesitation (is it understanding, or only imitating?) you're sitting exactly where Turing left us.
He left the question open. Honestly, so do we.
