At that advanced age, due to ageism in the tech field, by the time it failed, she would be lucky to be hired as a people greeter at walmart, much less be permitted to "ultimately do something great". At her current age, she will be OK. You can do great things as a retail cashier, or a waitress, its just easier to do great things when your job has at least something to do with it.
