I disagree.
Because different cameras facilitate different types of pictures. Partially through ergonomics, partially through technical capabilities, and partially because these overlap.
An iPhone SE has a different picture making envelope than an 8x10 large format view camera, and both are quite different from the latest full frame DSLR (which offers different ergonomics and capabilities than a similarly sensored mirrorless).
What I would say is that the camera is among the least interesting aspects of a picture…not the least interesting because the color of the photographer’s pants is objectively less interesting.
The focus on cameras is in part because shopping is easier than making pictures.
And the ways in which better cameras are described as better is usually by parroting the marketing points of camera manufacturers…the sharpest of corners won’t make anyone weep.
