Why shouldn't Socrates and Einstein meet? IIRC they did in Bill and Ted. Having an 'AI dungeon master' entertain fictional scenarios hardly debunks anything.

  Because the point of commonsense reasoning (which was the defining purpose of CYC) is that it is common sense that people (and other physical objects) have continuous paths through time.

    That seems to suppose that it's not possible to apply common sense reasoning to fictional scenarios. Asking the system whether a scenario ever could have happened is not the same as asking it to imagine an impossible scenario. The system's willingness to consider impossible scenarios doesn't mean the system believes those scenarios are possible.

      I worked on CYC (in fact I designed all the low level datastructures and the level architecture) and indeed it was an amusing bug in the higher levels of the system. Certainly CYC had no sense of fiction (when I was there) which is a very important function I agree, but that wasn’t within the project scope, at least back then.
