people use graphical interfaces because they don't want to type for things. i'm not sure people (particularly older citizens) would like to type to the OS. and a lot of people don't like to talk to their computers instead.
I predict chatgpt will be integrated with windows in less than a year.
having said the above, imagine if you could give natural english instructions as a script.
for example "install latest nvidia driver and disable all optional components" or "change my dns to 8.8.8.8"
it could allow non technical people to write automation scripts... and make some jobs redundant i'm afraid
