This sounds like schizophrenia to me. Particularly the weirdness and occasional paranoia. There’s no agreement on the causes of it, as far as I know. Whether AI can either cause it or push someone over the edge, I have no clue.

My brother has schizophrenia and is one of the most technologically inept people I know - both before the symptoms and currently. It is known to have existed well before modern computers.

Also worth noting that schizophrenia onset usually occurs in adulthood with and average age between late teens and early 30s. Later onset is less common, but known to occur.

A social security number/card is not exclusive to citizens. Green card/permanent residents, for example, usually get them - particularly, if planning to/already working.

Any kind of national/citizen id would need a whole new process and require it be provided to 100% of existing citizens. Time-consuming and certainly a cost associated with the process.

It’s one of those “in theory” easy things, but a lot more difficult in practice, I imagine.
