I am mildly fascinated by the types of issues that appear and the contrasts with other things that can locally in space and time look right.

An object doing nothing will have a consistent surface and show perspective relative to the viewpoint. The systems are able to have representations of surfaces of different types and how they can fit together within an object. I am of course talking about within a given generation, not between generations where its utterly unsurprising that consistency is very difficult or impossible.

But multiple objects in interaction with each other do very strange things. Their relative sizes change as if they are in different positions relative to the camera. They snap between individually plausible relationships, without going through intermediate states. Doors open on the hinge side when the other side is not visible. The relative size of and distance to the background can suddenly change, as the foreground suddenly interacts with something that should be far in the background.

Objects that change also do so in bizarre ways. Living things morph between different archetypes. Flames in particular change wildly between types and sizes and respond to the facial expressions of humans, smoke and water effects blend together. Sudden movements with no cause occur, sudden morphings of one object into another when the context around them changes and something else makes sense, especially when held in a hand. Time-reversed motions occur mixed in with time-forward motions, and slow-mo with regular time. Debris suddenly appears from an object but when the dust clears the original fails to have been eroded away into the fallen debris.

On multiple occasions, a carried candle keeps moving with a characcter rising and falling with their footsteps hovering in front of them when both hands become occupied with other tasks. This is fascinating and indicates that the relationship between the two objects motion is represented separately from the idea of something being ‘carried’. (This is positively Lovecraftian.) Candles also indicate something else, with flowing wax changing wildly in timescales that do not make sense, with the system apparently understanding that there are different patterns but having no idea how they come about or change. There is no generality here, just an endlessly compounding list of rules of thumb.

Excessive correlations between objects across the frame are rampant. Footsteps preferentially synchronized. People in the background lipsyncing with foreground characters, faces changing expression in unison. Textures changing across multiple objects at once.

I have said it before, and I will say it again, the relationship between the outputs of these systems and what they mimic are precisely the relationship between a stick insect and a stick, or a social-parasite-beetle and a baby ant. Not just in form, but because that is also precisely the same forces that drove both things into existence - superficial resemblance to something else with a very different internal set of causes, that can fool to a first inspection by the inspection applied but just isnt doing the same thing. And again, SCP-2030 feels the same.
