“Every day, I come by your house and I pick you up.

[DavidCroquet]

IMO the whole “solidgoldmagikarp” thing—being some old, unparseable term for earlier AI that would prompt them to return no response or just plain gibberish—is a metaphor for individual inability to parse the world around them.

Spoiler:  (click to show)(click to hide)

The movie sort of hoodwinks you with “both sides are bad”, but it’s really about how the characters involved don’t even comprehend what they are seeing and hearing and have unpredictable responses…in the same way as referenced AI described above. I think a lot about the scene where the blond girl is lecturing the black cop—her supposed ex—about how he should join the BLM side, and he’s looking at her with daggers in his eyes. But its not actually daggers or anger…he’s wondering wtf she is talking about, because his perspective is that they barely even know each other. His reaction is both confused, and confusing.

(The movie already established this kind of “misunderstanding” between Sheriff Joe’s wife and the mayor: one side thinks there was some pivotal life-altering relationship, and the other only recalls a couple unremarkable dates)

The last scenes, IMO, really push the audience into this place further, with the unbelievable left-wing murder squad showing up quite literally out of nowhere, and finally the sheriff’s mom sleeping in the same bed as him while making out with his in-home nurse who is also in the same bed. It’s “unparseable” to us.
