I think it’s more about how we think about the Turning test and how we use it as a result-- a hammer does a pretty poor job of installing a screw, but does that mean the hammer was designed wrong?

Turing called this test an “imitation game” because that’s exactly what it was-- the whole point of the test was to determine whether a system could give convincing enough responses that a human couldn’t reliably identify whether they were speaking to a human or a machine. Cleverbot passed the Turing test countless times, but people don’t ask it to solve their homework or copywrite for them.

From the wiki article on the Turing Test:

The test results would not depend on the machine’s ability to give correct answers to questions, only on how closely its answers resembled those a human would give
