A time dilation tool from an anime is discussed for its practical use on Earth; there seem surprisingly few uses and none that will change the world, due to the severe penalties humans would incur while using it, and basic constraints like Amdahl's law limit the scientific uses. A comparison with the position of an Artificial Intelligence such as an emulated human brain seems fair, except most of the time dilation disadvantages do not apply or can be ameliorated and hence any speedups could be quite effectively exploited. I suggest that skeptics of the idea that speedups give advantages are implicitly working off the crippled time dilation tool and not making allowance for the disanalogies.

The above comment would be insightful if it was a counterexample. This means it is not a counterexample. That means that it is not insightful. That means it is a counterexample. It's like the least interesting number paradox of nonsense strings of letters.
Regardless, I might recognize the technical accuracy of your point, but your point is only superficially useful. I liked the original comment and thought that it was both funny and insightful. Yes, some of that insight is mine as well, rocks can't sing or dance or use logic, but that doesn't mean that the initial comment isn't also interesting.
This does not follow. You're treating the first premise like a double implication, but it's certainly not true that the comment would be insightful if and only if it was a counterexample.
Clearly the comment "afsd;ljkurjzvn,x" was just a typo for "afsd:ljkurjzvn.x", which I read as agreement with my point, making clever reference to complexity theory and Aaronson's refutation of the waterfall argument.
