I wouldn't really care either, but there are probably people out there who do. I think it'll happen (if it hasn't started already), since databases & information systems are used for almost everything anyway these days. They'd just have to be as equally secure as systems that carry other personal information i.e. credit card numbers, bank account numbers, SIN/social security numbers, etc.
A hacker breaking in would be no different than someone sneaking into the room containing your medical record.
