Her biggest blocker is that she's terrified of making a mistake and breaking something. She would never dare explore a settings menu and tweak things just to find out what is or is not possible. So she calls her relatives to help her with the most basic of task ... and this has been going on for 40-50 years of her life.
I wonder if she had been introduced to computers younger in life if that fear of breaking things could have been overcome and replaced by a curiosity and enthusiasm to explore the digital space.
I'm also open the possibility that this fear is a personality trait and impacts her in other areas of life as well. We are just trading anecdotes after all ;)
