Sure would be nice to somehow know how many people ditched their cameras for a mobile device, these sales numbers hold no correlations today for that.
It would also be nice to add preorder numbers to the camera sales numbers, since supply is so difficult over the past 2-3 years.
All we have are marketing sales numbers of X vs Y, and no preorder numbers, or any metric at all that shows photographer A switched from camera to phone.
Even a poll just here on POTN wouldn't give that number, because if someone has moved to a phone for photography and ditched their gear, they likely would have left the forum, and in fact many already have for "greener pastures" of other social outlets, even if they still use their gear.
Like so many other statistics, 10 people might be able to draw up 15 different conclusions, with none being completely right, and maybe all being slightly right.
The end of the DSLR (and now mirrorless) has been circulating for 5 years or more. Yet here we have manufacturers still producing new products, so yes the numbers shrink for a number of reasons.
I think that is a good thing. That means my results might stand out a bit more for higher quality work vs my competition in the area. I saw the same thing when Rebels were on sale and people rushed to get them, and we had a rash of "I am a photographer for senior, event or family photos", only to see so many of them fail because they thought just getting a camera was enough. Ditto with phone users, and in many cases, the results are now even worse.
