Reliably correct is when you're correct always.

Agreed, except I add "almost". "My car reliably starts" it starts "almost always": more than 2 in 10 times. "You reliably turn up on time" doesn't mean you're late 8 in 10 times, it means you almost always turn up on time. To "almost always", or "reliably" a thing: it means you fail 1 in 100, in a 1000, in 10,000 times. 10k is hyperbole, but the idea is clear right? Almost always/reliably != failing 8 out of 10 times.

Your original point that these bots, that pass 2 in 10 times, reliably pass was wrong. Because: they dont "always pass", they don't "almost always" pass, they dont, even "pass in the majority of times", they rarely pass.

Let's add our reliable = always substitution to the quote:

Turing test can be [always] passed by a bot that repeats last part of the previous sentence with a question mark at the end [...]

You see how that's wrong not just in fact, but in spirit too?

If a person murders people only two days out of 10, they're a murderer, in order to not be a murderer they need to never do that.

Relevance? Who says "Fegenerate is reliably a murder?"

Demonstrably incorrect is when you're incorrect even sometimes.

Relevance? You didn't use the word "demonstrably passed'. I'd have no problems is you did?
