So? Tons of millennials barely understand technology too. I'd say a politician being one makes the odds they know tech marginally better, but I still interact with people of my generation that barely know what a filesystem is, let alone how to make one, or why it's important.
The joke used to be that Boomers don't understand the internet, even though they invented it.
Based on that experience I guess it should be no surprise that now Millennials don't understand the web even though we were born on web 1.0, grew up on web 2.0, and created web 3.0.
