I think you may be generalizing a bit with the part about auto exposure and auto focus. Not everyone uses either all the time in the digital world.
The problem with autofocus is that a prism focusing screen can screw up your metering. I would love to have a good focusing screen on my K-x but I can't afford a screen that won't screw up the metering. If I had a good split prism I could do without AF.
And I don't have a problem with exposure. On my last vacation, it took me about 4 hours to organize, grade, and do all post processing on 1700+ photos. I did it on the plane ride home and had a slideshow ready to go by the time we landed.
Part of that is shooting RAW as mentioned above, but another big part is shooting in M mode. When you shoot in M mode, you get the same control that the MX gave you, with a big difference. Your thumb index finger do the work while your eye never leaves the cup, you can change iso without changing rolls, and at the end of the day, you do get more flexibility and control with digital.
Most of the time, a shutter, aperture, or sensitivity priority mode will give you the wrong exposure because it's trying to make a dark scene light, or a light scene dark. With manual mode you get to pick how much over or under you want it to be. Once you get acquainted with how your camera's meter works, you start using the EV dial a lot and then finally you just graduate to M mode.
Here's a picture that I think came out really well, reflects the reality of how the scene looked when I was there, and which required (as I recall) no post processing at all.
I think there's been a democratizing and commoditizing of photography. The fact that the number one camera in use on flickr is the iPhone 4 should tell you something - the fact that professional tools are in the hands of more and more unskilled and/or dispassionate people. So yeah you get a lot of spray and pray out of folks, but modern cameras haven't made it impossible to take pictures like you used to. Has it advanced photography?
I guess my point is, the advances that we've made sometimes fail (AF in low light, program exposure etc), but they don't often. When they do, a skilled photographer can still use his eyes and fingers to take a good photograph.
