The Turing Test Is Dead
Hofstadter's diagnosis of the 2025 moment — the behavioral criterion Alan Turing proposed in 1950 has been effectively satisfied by systems that do not think, which means the test, whatever its historical utility, no longer distinguishes the phenomena it was meant to distinguish.
Alan Turing's 1950 paper replaced the question 'Can machines think?' with a behavioral test: if a human interrogator communicating through text could not reliably distinguish a hidden machine from a hidden human, the machine should be treated as intelligent. For seventy-five years the test served as the informal benchmark of AI research. In the winter of 2025, it effectively died — not because it had been decisively passed or failed but because the question it asked was no longer the right question. Claude's conversational outputs were, under ordinary conditions, indistinguishable from those of a knowledgeable human interlocutor. Segal described being 'met' by Claude. The behavioral evidence supported the feeling. If the Turing test was the right criterion, Claude had arrived.
