I think that you are absolutely right that the dig folks don't give a second though to film, which is fine. The thing that digital photographers will care about is the disruptions that are taking place in the digital camera world. I have bought a half of dozen point and shoot digital cameras over the years, a nikon d90, and a fuji X100s. More or less, they are all disposable cameras. My d90 is now electronically flaky, but it did well for many years. The Fuji worked for several years, but now can no longer properly retain the memory card. My satisfaction with Fujifilm in repairing it is nil (another story).
Quality film cameras can last a very long time (a real benefit to us dinosaurs). I do not believe the same can be said about modern cameras. Therefore, I believe the modern dig cameras are (like all electronics) semi-durable goods. A scheduled replacement cost of a dig camera body every 5 years is pretty steep in my opinion. I guess I will be looking to replace the X100s, but with what? I'm not excited about laying out $1000+ for what might well be a 5 year camera. I might just keep shooting film and get by with my old iphone for dig pics.
I doubt current digital photographers will migrate to film because of dissatisfaction with the state of the digital marketplace. I bet that there will just be an overall contraction in the world of amateur photographers.
