This job is aimed at people who make infrastructure software. I work primarily as an infrastructure SWE and although the community of people who work on such products is bigger than in 1994 it's still pretty niche. To a lot of folks the knowledge you need to have is viewed as esoteric. The web has spawned off a number of jobs that are abstracted above the system level that require very little deep integration with the system(s). DevOps, web backend devs, web frontend devs, designers, etc all live a layer or two of abstraction above building OS tooling and services that serve as significant a purpose as the webserver. That's to say, he knows who he's talking to.
