The newest iPhone and Pixels have much larger sensors than older phones. That is the reason for the hump on the back. The sensors are bigger, and better, than digital compacts. They are half the size of the 1” fancy compacts and with newer sensors might be better.

The only difference with compact cameras is not having zoom lenses. But the telephoto and wide cameras on some models help make up for it.

There is a big jump to interchangeable lens cameras. But those aren’t what is popular as vintage.
