Very true and not widely understood by people. Increasing pixel count trend is common in DSLR as well. If anything it makes processing difficult without upgrades to computer. There is a place for high pixel count but i don't think it's required by most.
Said that modern smartphone cameras are pretty good for normal snapshots. On trips I use a DSLR but phone has replaced need of any other smaller digital camera. If photos have to be seen on phone itself or social media, then phone cameras do a very decent job.
