Short answer: They'd probably try to hire a live-in caretaker. I don't have to babysit her 24/7, but having to be with her for a few hours almost every day does limit my ability to, say, go off to an all-day Magic tournament. It can't be any more restrictive than having an actual full-time job, though.
Actually, it sounds more restrictive than a full-time job, in the sense that most jobs involve a significant amount of social contact, and most decent ones also involve some degree of ongoing exposure to new ideas, too, so there's a significant chance that you'll be exposed to something you find interesting enough to get involved with on your own time, and your situation doesn't involve either of those, and interferes with your ability to pursue such things on your own time.
