I used to do that when I was a teenager and it was truly wonderful. I had my own darkroom and was even developing my own film (BW only). As tech evolved I moved on to digital but took so many photos that somehow I stopped caring about photographs at all. It even became a bit overwhelming to look at photos and to some extent it still is to this day. I took on many other hobbies so it's not a huge loss for me. But I can totally get why some folks would get back to film from digital, they're going for the experience and not the end result as photos, which I agree would be more efficient to process digitally. But same goes with other arts. Why are people still painting? All can be done digitally in Krita or some other software and a lot more efficiently and faster and so on. And yet people pay money for canvases, oil paints, brushes, and spend hours and hours painting.
