The point is not that there isn't a point of overlap, the point is that the digital world can go many more places. Every digital camera I've ever bought has come with photo manipulation software that may include various physically-inspired tools, but also goes above and beyond what can be done in analog. Any company that tried to be just "analog photos, but on computers" would be stomped in the marketplace. I have found digital photography to be a qualitatively different experience than analog photography for over a decade now.

(Which isn't to say the digital experience is all pros and no cons; photography has held on to some "pros" longer than many other fields.)
