One of the most interesting traits of the No-God is the seeming disconnect between its actions and statements. While its statements perhaps signal a sort of existential confusion, its actions are precise and show clear intentionality, which is corroborated by various accounts (Aurang's, Skafra's, to an extent Wutteat's) testifying to the agency of the No-God. It does things, it's not just a predetermined algorithm, at least not from the point of view of its intelligent servants. It possesses all the common signs of intentionality in its actions.

The issue, thus, is in its statements. I would say that this disconnect outlines Bakker's original framing of the philosophical zombie thought experiment - here, the aforementioned zombie is behaving intelligently, but, if we're to go by its own account, doesn't recognize it itself. It lacks a crucial something that makes humans human, the exact something the philosophical zombie experiment endeavors to pinpoint. I'm currently unprepared to make any assumptions as to how that might work or what it might ultimately mean.

Returning to the question at hand, my guess is, any further pronouncements of the No-God would only strengthen the framework of Bakker's take on the philosophical zombie idea. One thing I want to note is that I don't believe the Insertant retains in any way enough identity to impact the System while it's operational, although maybe at the end of the cycle, when the System is less stable, that might change. During the First Apocalypse, the No-God was active for nearly 12 years, and the number 12 appears to be thematic for both TSA and the Book of Revelations (the biblical Apocalypse), being present in the much discussed 144000.

Not sure if we've ever figured out why the original insertant and lil' Kel were able to operate TNG. We've been talking about it in Facebook and bringing it here in case some of you are not in the FB group. Could it be that a twin killing their twin causes their consciousness to collapse with their unconsciousness which then makes you invisible to the gods since you wouldn't have a soul any more ( soul destruction? or does it go somewhere? ). If this happens to you, then your conscious and unconscious minds would be objectively aware of each other and can even talk to each other. So the original insertant and the dude 2,000 years ago ( forget his name ) were both twins who murdered their twin, obj/sub collapse, their soul is gone and then can operate TNG. TNG is invisible as well as the insertant is - explains why the Luck Warrior couldn't see Lil' Kel, was invisible to the gods since his ojb/sub collapsed. So back in the day, the Consult couldn't figure this out and just sent a horde of people through trying to find someone who could turn it on. If they knew this was how to make it work, they would've simply found twins and engineered one to murder the other.

One thing that I want to say about  it (it came up on Discord recently) - there is no data points that suggest that there were any Insertants before Nau-Cayuti. Thus, he is the original Insertant.

That should in all likelihood decrease with time, since random collision events, not to mention the entire thing just can't be that stable (especially while also moving), 'cause, you know, physics.

And this is why I think that they didn't wait because there was nothing to wait for, meaning the Chorae are no longer needed and not just removed for the sake of a prospective Insertant.

Speaking of the Dunyain all having Anasurimbor blood - I think Bakker is making an effort to counter this argument when he talks about the Twelve Germs (if memory serves), of which the Anasurimbor one is the most promising. Since the Germs are pointedly named as different from each other, I get the idea that the Dunyain in their generational selection quest were strict about keeping the lineages separated.

I'm firmly on the "not enough data to draw conclusions" train.

This seems to be about things different - and perhaps more - than simply Hell.

and there was some mention in the one of the books or Tales that the Inverse Fire never shows the same scene of torment twice...

More specifically, the Inverse Fire is projecting atemporal onto temporal, which isn't going to be in any way straightforward, or even complete, to perceive.
