How did we get where we are?
Dont let the wheel of progress run you over as it passes you by. Just because we aren't doing it doesn't mean we can't do it (which is not the same as change for changes sake).
ATC over the years in Australia has changed greatly since I have been involved some for the better some for the worse.
I have to put my hand up and say if the system can support it - generic ratings would work. I too am quite happy to yearn back to the yesteryear of control when the sky was dark with Dc9s and Sydney only had 2 (is it 4?) runways (well it will again but that is another thread) but as the technology becomes more advanced and the tools and aids that we use become better suited to the application required I fail to see why generic ratings - within reason - cannot work.
Upper Airspace and Arrivals are two that would be ideal for it. I agree it is not for everywhere, hard to have a generic tower rating at say Cooly and Hamilton Island (although I would be prepared to commute!).
I suggest you do some research on what ATC is.
