This thread blends the ideas of consumerism with the more utilitarian goal of suitability to a particular task.
Cameras are largely a consumer product, and as long as people have wants there will always be a market. Especially for those who are in the endless pursuit of “better” whatever that actually means.
But someone who is good with a camera tends to seek specific goals. As examples, does the camera work well in low light, does it offer a large sensor and produce a large enough image for the print size desired, is it light weight, yada, yada…
As long as a camera is suitable to a task or a number of them there is no utilitarian need to replace it. For some, the cost (more the better) and bling appeal *are* utilitarian needs. But of course those are really examples of consumerism.
If one identifies a part of them-self closely with a camera, they may well have an endless pursuit of having the “best” camera they can get. It may be based in utilitarian need or the need may the perfect confluence of consumerism and suitability to a particular task, when the “task” just may be little other than the appeal to vanity.
Anywho, people desire “better” in all things, so the answer to the OP’s question is an unequivocal yes.
