“Granny” has evolved. In 1985 granny at the tender age of 60 was born when 65% of households didn’t have electricity and she came of age when the height of sophistication was the typewriter.
In 2010 granny saw computers become a thing when she was 40 become usable by 55 and pervasive at work by the time she retired.
In 2024 granny saw computers become a thing right when she became an adult. Her kids had them. She used them. By the time she was 46 they were literally everywhere and unavoidable
By 2034 granny saw computers become a thing when she was a kid and they were everywhere by her early adulthood.
This isn’t an argument against GUIs which are in fact useful but lets not pretend everyone is an idiot either. Honestly I don’t find googles GUI for managing android apps even slightly usable as far as finding software either. I always end up searching on an actual search engine, finding the exact app I need and then installing it. Android with its mega millions of users doesn’t have a better ux than apt.
