Everyone I know is able enough to administer their own gizmos. If someone asks, I point them to the zero config option that will require zero tech skills. Computer maintenance is mostly unskilled drudgery nowadays, not wizardry.
Computer maintenance doesn't exist for most people I know. If something gets slow or stops working, they ask a friendly wizard to magically fix it, or they buy a new/different thing, or they do without. It's not that people have learned to admin their own devices, most devices just don't have proper administration.
