OpenSuse is essentially free marketing for SUSE, nobody would know them otherwise
I’ve been working for big enterprises for many years, SUSE is used in enterprise environment to run SAP systems because it’s recommended by SAP, OpenSuse has nothing to do with that.
Many years ago at work, when PCs started to spread, I taught a 60 years old lady how to use one. She never saw a PC before yet she learned pretty well, and I saw much younger people not learning.
Being willing to learn doesn’t depend on age, it’s a mindset, either you have it or you don’t, and if you do have it, it will last your entire life.
