For elderly people, an interface with options to have big icons and accessibility options would be very helpful; and accessing a program should take no longer than 4 clicks via mouse, or 6 keyboard keys.
GNOME interface succeeds well in that, as you can click Super key and be able to search between all the existing apps. Or the top left Applications menu could be used to browse through all programs.
For beginners in tech; GUIs for installing programs would be a big help. New people might see writing console commands for installing programs complicated, compared to other OS’s show their app stores in a visible location. Also do not make users search for graphics drivers.
