That hasn't been my experience. I suspect that most others who also daily drive linux would find it remarkable if someone used Linux every day for a year and never needed to open a terminal to install anything, fix anything, reset anything, update anything, follow any instructions given by any software they found and wanted to use, etc.

My parents have been using Ubuntu for 15 years continously and never used the command line a single time, I even had to retire the computer first as it was too old.
