There are many posts here that have accurately described the viewpoint espoused by the New Yorker blogger. As do others who have posted, I also believe that his article overgeneralizes what photography is and overemphazes the need for immediate transmission to the web from the capture device..
Those active here are interested in photography itself as a pursuit. We are more interested in advanced gear and in making more ambitious photographs (as well as the pet shots, grandma shots, etc. that we all shoot too, all of which are fine). I suspect that the subject matter of many of our photographs ranges beyond documenting travel, family and life events and that we try to express broader concepts, points of view and aesthetics. Many of us still enjoy working with silver halide and even older processes. Some of us display our work primarily online, and some also still print to display our work. As long as there are enough of us to create sufficient demand for the products of camera manufacturers (and film producers), we will have advanced technology to produce superb quality photographs.
The author may once have fallen into the group of those interested in photography itself, but he no longer does. Although there are serious hobbyist and maybe professional photographers doing excellent work with cell phones, there are many more using them for photography who have no particular interest in photography as an activity, but who want to record their travels, social gatherings, life events, etc. We used to call the latter group snapshooters. Mostly, they used Kodak Brownies, Instamatics, film disk cameras, and later digital point and shoots because these devices served their photographic needs at a reasonable price point. It stands to reason that this group would now turn to cell phones, which almost everyone carries and which have increasingly good quality and the ability to share photos immediately.
The author of the New Yorker piece seems to believe that all photography is confined to the shapshooting world. Probably the vast majority of photographs are made in this mode; however, folks like us also are still around. That seems to have escaped the author. Nothing wrong with his view of things, but it is just incomplete.
Also, I'd be astonished if the camera companies don't include better connectivity in all camera models, whcih eliminates what the author apparently perceives as a fatal technical flaw. Not all of us feel the urgency of sharing our work so quickly; however, I suspect that we will soon have the ability. In fact connectivity already exists at least in rudimentary form in many mirroless system cameras today.
