I don't mind it at all. I'm enjoying school. Totally agree with likkriue. Don't see why it's crazy and dystopian to imagine a future where dentists aren't arbitrarily sectioned of from the other guys.
An ophthalmologist would consider it an insult if you talked about him the way some dentists talk about themselves, and it's not like his potential areas of speciality/subspecialty are any broader than the various dental disciplines.
The difference is that they don't bitch when they have to learn more background info, mostly just because that's the convention in their profession; they're expected to be MDs -> ophthalmologists.
But if you rewound history, it could well have just turned into a residency after optometry school or something.

In the mean time, I'll enjoy the primary upside of our current peon status - the severely reduced regulation. My MD classmates have so many more hoops to jump through when it comes to setting up a practice or making big treatment decisions.
