Oh, absolutely. My favorite conversation to have with non-techies is
"It doesn't work."
"OK, what does it say on the screen."
"I don't know."
Like, they can read. I've seen them read. But the moment they get something on the screen with text they haven't seen before they freeze. And even if they can read the plainly written text saying stuff like "hey, we need to install something, is that fine?" they can't parse what is being said. Half the requests from help I get from people are about them getting a prompt to update something that needs manual permission and them being too insecure and scared to know what they should do.
So yeah, the bar is much lower than people think. As in, the question "Do you want to do this thing you have to do and is fine to do? Yes/No" is an unsurmountable obstacle.
