I've been pondering the same thought recently but applied to analog cameras. Analog cameras have evolved over time, approximately according to the following:

- fully mechanical

- mechanical shutter with light meter

- electronic control of shutter, mechanical advance

- fully electronic shutter and advance

Broadly, what I'm finding after digging in to restoring some cameras is that most of the cameras from the first stage can still be fixed and made to perform close to when they were new. The second still work, but the light meter can die (simpler light meters may be repairable, later ones not so much). The third and fourth stages - once they die, there's no repairing them. And when you look at digital cameras, there'll be very, very few of these that last long into the future.

This bears out the 'Lindy Effect' mentioned in the article.
