This comment seems completely at odds with history and how people actually acted prior to the smartphone revolution.

Film camera sales proceeded on a steady incline from their invention until the introduction of the digital camera.

Digital camera sales increased year on year for every year of their existence prior to the introduction of the smartphone.

Approximately everybody wants to have photos of their precious memories, and the idea that people wouldn't have kept buying digital cameras if smartphones didn't incorporate them is, to be frank, a little bit silly.

The primary difference between digital cameras and smartphones was that every family I knew had a digital camera, where every person I know has a smartphone. And every single person I know uses the camera on their smartphone very regularly.
