It is called "creative destruction" by the economists. A new technology comes along and replaces an existing, mature, technology. Whenever the new technology appears, it is limited compared to the old and it takes time for it to develop. When dry plates first appeared, they offered the advantage of being portable and they could be developed long after the shot was taken. Initially, they were slower than wet plate and not as good a quality. The advantage of not carrying a darkroom around with you eventually won out, but it took time. For those serious about quality, it took longer than the "early adopters." Film offered advantages over dry plates, but the quality was not there initially. As the quality improved, more photographers started to use it. Same with digital. Initially, the quality wasn't as good as film. Remember the Sony Mavica? It was a breakthrough camera, but not anywhere near the quality of film. It was also expensive compared to film cameras. As the quality improved, and the price dropped, digital won the hearts and minds of most photographers. The instant feed back and ability to send the image instantly to a client changed the work flow of photography.
The history of photography can be a case study of new technologies slowly developing and taking over existing technologies. The image quality of the daguerreotype was far superior to that of the paper negatives. But as the quality of paper negatives improved, and as wet plate work improved, the daguerrotype faded. Salt prints were replaced by albumen. Albumen was replaced by gaslight. Gas light was replaced by enlarging papers. Enlarging papers are being replaced by printing technologies. Wet plate was replaced by dry plate, which was replaced by film which gave way to digital. With each transformation, some adopted the new technology early, before it matured, while others clung to the old because of its advantages over the new.
