This might be one of the failure modes of the current incarnation of capitalism. My Canon cameras last me forever and that's why I like them. I consider them a blazing technical and scientific success.
If under the current mode of capitalism they want to "succeed" financially they might need to make crappier cameras on purpose so that people replace them every year.
Crocs are also amazing. I bought a pair and never needed to buy another pair. Bad for their balance sheet, but they are an amazing success in terms of sustainability and not creating trash.
Mean time between cameras has probably been increasing due to the very high quality of DSLRs for a decade now. Upgrades aren’t really worth it and there’s better things to spend money on if one wants to improve: lighting, triggers, lenses, supports, and travel!
Film cameras used to last a very long time in the range, Nikon, for example, went from the F to the F4 in forty years. Around ten years between the pro cameras. That’s down to about four years now. My 1DX shows no signs of needing replacement, despite wanting WiFi and GPS, everything is great, and despite fewer pixels than the previous 5D2, enlarges to wall-size without drama. The iPhone takes care of casual use, and a £110 Fuji XM1 covers everyday carry. A secondhand digital camera from six years ago is good enough and costs around £100. Well, why upgrade indeed?
