If I can teach my aging mother(57) to use standard ubuntu 18.04 as her first computer ever then anyone can learn linux. Everything she needs is clearly presented in the bar of application icons and the ancient scanner/printer someone gave her works perfectly. Bonus points for when I go visit and there is a handful of .exe's hacked facebook friends convinced her to download sitting uselessly in the download folder.
