@sun @Hyperhidrosis also

The SSN was never intended as a primary key, the concept of a primary key didn't really exist, and it should never be used that way outside of social security(do y'all even still have that?). It should be used as a social security identifier that's it.

it's abused if it's used for *any* other purpose by the US govt including whatever musk is doing to them, just like the SIN is abused by every government department here
