Grew up without one? He’s 80. He probably didn’t even use a computer before he was 50.
Pretty sure there were computers in the eighties.
I can confirm. I have touched several of the computers sold before 1990 in my lifetime.

To be fair, many people didn't use computers much, back then.
I’m basing my comment on my life experience of growing up in the 80s and 90s. Most people in the time period did not use computers. A lot of people thought they were nerdy. So someone like Joe Biden who is a “cool guy” politician almost certainly never touched one until he needed one for work. Total supposition on my part but I would put money on it.
