I think you’d be surprised how much phones have encroached on the fancy camera space. Also, the limiting factor in phone camera quality is more the lens than anything else. The SW backing it is much more powerful than what you get in standalone cameras although those manufacturers are trying to keep up (that’s why phone cameras can be so competitive with more expensive ones). I expect within the next 10 years we’ll see meaningful improvements to the lenses used in phones to the point where dedicated cameras will have shrunk even more (i.e. decoupling the size of the lens / sensor from the surface area on the back of the phone).
