No modern AI has been able to reliably pass the Turing test without blatant cheats (like allowing the use of foreign kids unable to understand/express/speak themselves fluently, instead of adults). Just because it dates back to the 1950s doesn’t make it any less valid, imho.

I was interested by the other tests you shared, thanks for that! However, in my opinion:

The Markus test is just a Turing Test with a video feed. I don’t think this necessarily makes the test better, it adds more requirements for the AI, but it’s unclear if those are actually necessary requirements for consciousness.

The Lovelace test 2.0 is also not very different from a Turing test where the tester is the developer and the questions/answers are on a specific domain, where it’s creativity is what’s tested. I don’t think this improves much over the original test either, since already in the Turing test you have freedom to ask questions that might already require innovative answers. Given the more restricted scope of this test and how modern procedural generation and neural nets have developed, it’s likely easier to pass the Lovelance test than the Turing test. And at the same time, it’s also easier for a real human to not pass it if they can’t be creative enough. I don’t think this test is really testing the same thing.

The MIST is another particular case of a more restricted Turing test. It’s essentially a standardized and “simplified” Turing test where the tester is always the same and asks the same questions out of a set of ~80k. The only advantage is that it’s easier to measure and more consistent since you don’t depend on how good the tester is at choosing their questions or judging the answers, but it’s also easier to cheat, since it would be trivial to make a program specifically designed to answer correctly that set of questions.
