Honestly, I went out to Marin Headlands this morning to photograph the sunrise, brought my 60mpix fullframe camera and some amazing lenses. But while waiting for the best light or long exposures I snap off a couple pictures on the phone. And I was just thinking, if I'd just post to Instagram and not print, I probably wouldn't even bother with the fullframe camera - a nice hike without 20lbs of gear and as great photos if you don't need the resolution/detail. HDR+ and the other computational photography goodness makes for great photos straight out of the phone and a tiny bit of editing then goes long way.
I bet if you showed 20 non-photographers 2 images a phone screen, one from the phone and one fullframe edited, most wouldn't appreciate the difference.
That said, I wouldn't give up my camera for many shots but I can understand why many people do. Post-processing camera raws is definitely more cumbersome than quickly editing photos on a phone.
