In general I agree with what you're saying. But lets also consider that since the "cost" of an image is much less and effort to take is much lower people now regularly do things like take pictures of every single meal, drink, etc. Previously people would have had to brought the camera and/or go get the camera and many did not bother.

Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
