Yeah, I'm a millenial even and I know people my age who didn't have a computer with internet (at home) until they went to college. People really underestimate how insulated some rural communities are, especially impoverished ones. Most of my family still lives in appalachia, and when I visit there are a surprising number of places where you barely get phone signals from any major networks. DSL and cable internet is still unavailable at my grandparents home last I asked.

From a different angle, a good friend of mine who is now an excellent engineer was denied a computer with internet access for totally different reasons during her high school years. Her fundamentalist parents thought the internet was immoral. She couldn't even have a game console, because her parents said those were for boys.

But yeah, asking people that question basically assumes that the answerer had a degree of privilege that isn't nearly as "average" as the asker would like to believe.
