A difference worth noting is that fewer and fewer photos get printed today. Most of them are only ever viewed on phones or monitors or panels and the content is what seems to interest the general public, not the detail or nuances. Those interested in photography buy DSLRs, the rest of us use phones or point and shoots.
One parallel is what is termed the 'democratisation of computing.' Once upon a time the only ones able to use computers were specialists with 'pointy hats and magicians robes'. Then came the PC and desktop applications that opened the wonders of computing to masses, which over time dumbed it down to the 'app' where the user no longer needed to be an expert yet had awesome capabilities open to them.
Another is the MPx digital format that has all but totally taken over delivery of music. Some of us still prize vinyl, some the CD, but music is increasingly delivered and played on formats with varying loss of detail on systems that have evolved from the wonders of the pre-digital age for better or worse.
With the advent of the phone-camera people can take photos they would never have taken in previous generations because they never would think to carry a [bulky] camera everywhere. Most phone cameras tend to make acceptable but not great photos. After the fact photo editing and correction applications can make an ordinary photo into a decent one that is fit for purpose of display on a phone / PC / panel and even printing on a consumer ink jet. For those who crave excellence it can be had with DSLRs, and arguably the best of the phone cameras.
The common denominator is the smart phone. Each has the computing capability of a supercomputer of only 2 decades ago, in the palm of a hand not in a special purpose-built facility, for $100's not $10,000,000's. The phone for the masses is replacing the camera, music player, GPS, payment systems, video calling, things often done on a PC, and on it goes.
What do I look for in a smart phone? At some point each of us gets overloaded and just wants something we can understand that can do the things we want to do and usually a bit more just in case, but not so much more we get confused by its complexity or overbuy something with a life that is often considered 2-years (by the manufacturers). Eg, simplicity for what I want it to do with reliability and enough robustness to survive my pocket.
