This is behaviour trees. What you’re describing is behaviour trees.
Edit: I see later you say it isn’t a behaviour tree but this is how a lot of BTs are implemented. They don’t always loop from the root. A lot of the time according to state the root is redefined off of a branch and that sub tree is looped until going further down the tree or even into a different tree. Much like the stack you are describing.
Perhaps this explains why Fromsoft npc quests are easily the most inscrutable in all of gaming. Like, okay Hyetta, have another “grape”, aka eyeball, oh now you’ve moved to the bridge in Liurnia, cool. I’ve exhausted your dialogue but you’re stuck. Oh I have to reload the area and exhaust it again to advance your quest. Okay, cool. Now you’re in a random church and you want a “fingerprint grape”. What?
It’s all part of the Fromsoft experience but man, who writes these things?
I know very little about AI and game mechanics, but knowing how early Fromsoft games were (e.g., Kingsfield), a basic AI in Elden Ring is very unsurprising. That's not necessarily a bad thing!
My vote for "high tech game AI" would probably be this old mod for Fallout 4:
>PANPC (Pack Attack NPC Edition) is a unique scripted AI management system for Fallout 4. Rather than treating each enemy as an individual proximity-based reaction agent (basically, a mine with a gun), this system generates social feedback between NPCs belonging to the same or allied factions.
>Enemies factor the overhaul health and success of their “team” into their tactical decisions, adjusting their strategies based on their social and threat awareness. As a result, they will switch between ranged, melee, defensive, and offensive tactics based on their perceptions of team advantage and individual risk.
My favorite high tech AI was Crysis. Might have been an update after it was originally released. The enemies will aggressively attack but then get quiet after you've taken cover. Eventually you'll realize some of them are flanking you while others keep suppressing fire on you to stop you from moving. You can hear them yelling to one another. Very cool touches.
As a game dev, the fact "AI" as a keyword became totally unusable is quite annoying.

Low tech AI? Its sounds like standard game AI. I would really like to hear what the author would deem high tech game AI.
