People are still splicing movie film with razors and glue too. I wouldn't say it's a "different art form" any more than acrylic is a different art form than oil or tempura (paints in case you're wondering) -- indeed film photography + darkroom technique is closer to digital photography + Photoshop technique than oil is to acrylic. There are different tradeoffs, and for 99.9% (or more) of uses the tradeoffs favor digital.
