Given the progress of "computational photography" in smartphones in recent years, I reckon that everything between smartphones and professional cameras will be dead within rather short term. That is good news for the likes of Hasselblad, Leica (count them among pro), Alpa etc, because their business model is shaped towards this situation already. All others will be in trouble.
It really surprises me that none of the manufacturers have tried to combine smartphone with a better camera part. Such a "smartcam" could have full smartphone functionality and similar form factor, though sturdier, but a camera with an built-in lens mount (similar to those accessory lenses & cages available, but with electronic interfacing for improved functions in the lenses), a much better camera app than standard, including direct interfaces to social media platforms, and of course some dedicated buttons and dials for operating the camera, and a tripod mount.
Additional revenues could be generated -aside from the lenses- by offering upgrades and expansions to the camera app at a fee (Arri does that for the Alexa, you have to buy licence keys for certain functions), or accessories like a remote control or an EVF.
The main problem I see here might be the reluctance of Apple to cooperate with third parties, so that such a smartcam would probably have to be based on Android, which will restrict the reachable customers.
