His examples work fine but you aren't accepting them because they don't confine to your paradox.
Every writing must be comprehensible to at least the author, regardless of whether it has commercial value or not. If I hit the keyboard a few times, I've created writing, but it doesn't mean anything. It is just gibberish and without meaning, so there is nothing to try to comprehend. So if there is something to be comprehended, then at minimum the author should know it.
Therefore what you keep claiming is the only refute of your argument of "an [...] incomprehensible [...] writing" is actually a paradox, and cannot be disproved itself. However "humans comprehending things" is not a paradox, which means that your specific request to beat your paradox is not actually related at all.
His examples disproving the non-paradox version of your challenge (writing incomprehensible to folks other than the original authors) are sufficient to disprove your statement, as he gave examples of both people not comprehending human made and 'God' made writing (the universe/gravity)
That's because his examples are obvious and not at all interesting, since we've already seen them.
His original claim amounts to creating an AI that takes its place above humans as some kind of electronic God, delivering edicts to humanity that we cannot comprehend, but which somehow have value to us. It's unskeptical, pseudo-religious nonsense.
I don't see that at all. Nowhere did this person evoke placing AI above people or even remotely evoke religious imagery. You imagined that yourself, and that creeps me out.
It’s right here:
The age of humans comprehending things is coming to an end [1]

That does not place AI above humans and neither does it evoke anything religious.
Look at it this way. AI has destroyed humanity at chess for decades now. That doesn't mean we have placed AI above humans in the general sense.
You have basically totally fabricated what you thought the other person was saying.
