You might find it interesting to know that Richard Stallman has no idea how
to install any GNU/Linux system, because he always has someone else do it for
him:

This isn't exactly the same thing as using the system in a particular way,
but RMS also has expressed that he's not very good at using graphical
interfaces. I remember the video someone pointed to showing that RMS was
using Trisquel 6; he acted entirely confused by Trisquel's interface, and had
problems with his slideshow presentation I probably could have solved in a
couple seconds were it me. So, he's been the complete opposite of the typical
user in that sense.
Now, you can claim that the command line is just superior in every way to
graphical interfaces, but the fact remains that RMS hasn't fully learned to
use his system, and hasn't learned to install his system at all. So if you're
going to claim that all those other users who haven't learned to use the CLI
need to learn it, or else they're "stupidly lazy", surely the same also
applies to RMS and what he doesn't know how to do?
