Why not also pine over the passing of the
Collodion wet plate process?
For every technology, I'm guessing there is an even older one.
What amazes me is how much more "democratic" and egalitarian photography has become thanks to digital. Sites like this one, and strobist and Flickr connect hobbyists so well. Experimental lighting used to require light meters, experience, tons of film, perhaps special polaroid camera backs and so on. Now it's $30 for cheap radio triggers...
Others used to devote real-estate to darkrooms and chemicals. Now even apartment-dwellers just need a laptop and Gimp/Photoshop/what have you.
Also, just because you shoot digital doesn't mean you can't get out an old camera and shoot film just for fun. Heck, put some 100 iso B&W in it and walk around for a day. The constraints might make you learn something fun...
