Yes, I take a few pics on the phone per year but that's it. Looking around with friends and family I see the same. Again: I understand that there are lots of people that really do take lots of pictures and videos but I can't help but think that lots of regular smartphone users are not as concerned about the camera quality as the marketing makes me believe.
The best camera is the one that is always with you.
I used to argue the same, but this is no longer true. The cameras are really good now. Smartphone cameras have beaten point-and-shoot. They won't ever beat DSLR, but most people don't need a DSLR.
The future of the camera is the phone.
Before smart phones were camera phones and camera quality was a key factor mobile phobe sales. The original IPhone was hesvily criticised for its crappy camera quality.
You and your cricle might not take loads of photos on your phone but me and the gneral public take hundreds.
I think it's very possible that the use case for the people you are around most is as you say. This behavior is contrary to the majority of smart phone users, however.
I'm just saying - and it's fine for you to have a different usage type - that there are people around (even in "tech" circles) that are just not concerned about cameras, pictures and videos. And my feeling is (it's really just a feeling) that it's not clear how many there really are as most of these people are also not active on Facebook, Instagram, Flickr etc.
In other words: I guess my viewpoint is just as subjective as most of yours and heavily dependent on the people around me and you.
Additionally, given that most people only have their phone cameras with them and don't invest in SLRs/Mirrorless/Compact cameras, the need for good quality for preserving their memories seems important.
