If you prefer to carry a dedicated camera in addition to a phone, aren't you a far outlier? To the point that one of the most common sayings in photography is "the best camera is the one you carry" (even when it's the sub-par one).
"The best camera is the one you carry" is about opportunistic capture of moments i.e. it's better to record them on anything than nothing. That doesn't always work. I've lost more moments than I gained on a smartphone camera which won't focus on what I want, does weird uncorrectable things with white balance, has a pretty nasty digital zoom, or has gunk on the lens from being handled.
