Why do smartphones have triple-quadruple cameras when “dedicated” cameras have just one? What makes it better and why do we not see the 3-camera setup on actual cameras then?

On an actual camera you have the ability to physically move the lenses to zoom in and out with optics (you’re physically changing the distances between lenses and sensors). On a phone, you don’t have the space for this mechanism, so instead, they include multiple smaller cameras with fixed optical zooms.
I have a camera with a 50x optical zoom, you can see the camera physically extending to achieve that.
