In the post the woman is not the butt of the joke for being tech illiterate (and I’d argue they aren’t presented as that), the joke is on Anon for insisting on using free/techy stuff rather than costly but convenient things and ruining the vibe of the evening. This could just as easily say “Anon, why are you still fiddling with the picture settings? It looks fine. Motion blur? I don’t know what that is. It looks fine. Just watch the movie.”
