Huh...? This couldn't be further from the truth. They may not be terribly picky about the technical details about them, but actual human beings take photos... all the damned time.

> The trick to solve the camera problem is just buying a good camera that isn't your phone.

Coupled with your other view on this, it's not worth discussing how ridiculously inconvenient that would be for what people take photos for: social media.

This may not reflect your own usage pattern, but it sure as hell is what real people do with their phones. Taking pictures of their casseroles and making duck lips with their friends.

Twitter only has something like 70,000,000 active U.S. users, Facebook only has 244,000,000 in North America and Canada combined. That's nowhere near the entire U.S. population, and probably half of those take photos with their phones.

You're forgetting the dozens and dozens of other social networks: Snapchat, Instagram, even email and SMS get heavy usage in the US.
