To me I’m not really sure what his reply even means. I think it’s some attempt at a joke, but I figure the joke can be broken down into two potential jokes that fail for different, embarrassing reasons:
Interpretation 1: The government is so advanced it doesn’t use SQL - This interpretation is unlikely given that Elon is trying to portray the government as in need of reform. But it would make more sense if coming from a NoSQL type who thinks SQL needs to be removed from everywhere. NoSQL Guy is someone many software devs are familiar with who takes the sometimes-good idea of avoiding SQL and takes it way too far. Elon being NoSQL Guy would be dumb, but not as dumb as the more likely interpretation #2.
Interpretation 2: The government is so backward it doesn’t use SQL - I think this is the more likely interpretation as it would be consistent with Elon’s ideology, but it really falls flat because SQL is far from being cutting-edge. There has kind of been a trend of moving away from SQL (with considerable controversy) over the last 10 years or so and it’s really surprising that Elon seems completely unaware of that.

My guess is that he thinks SQL is an app or implementation like MS-SQL. It would be pretty surprising if the government didn’t use SQL as in relational databases, but if it doesn’t it’s even more unlikely that he understands even the first part over whether having duplicate SS numbers is in any way unexpected or unreasonable. Most likely one of the junior devs somewhere along the lines misunderstood a query and said something uninformed and mocking, and he took that as a good dig to toss into a tweet.
