Agreed, for probably <0.5% of the AE-1 of the cameras ever produced. That is my point that as innovation moves on, a few people (specialty market) will hold on the 'older' technology. Most users move on.
Right, no one is disputing that the majority of people will embrace technological advancement if it proves beneficial and affordable. Technology is not always marketable, but overall, history has proven that 'the new' will dominate consumer choice (and usually for very good reason!).
Then again, some people adopt because they have no choice; their preferred product is no longer available.
We know all of this; but if someone says they are satisfied with their current product, they are not invariably obligated to upgrade in the future purely for innovation's sake.
Obviously, photography has a lot of purposes and functions, and part of it resides in the arts, which can at one point certainly benefit from technology, but at another point, completely and happily ignore it.
Convenience is a huge factor in gaining popularity, and certainly as a film user, I heard my share of DSLR users in the process of disparaging film contend that hey, time marches on, digital is more convenient, more affordable, more this and that.
Of course, now some of these certain DSLR users are likely having to reconsider their own argument, as time is not marching in their preferred direction amid the encroaching impact of camera phones and mirroless cameras.
That is, maybe technology is not always for the better, at least for everyone. And this is my point. We can talk about the masses, but for the individual, consumer trends are largely irrelevant in regards to their personal taste and preferences.
And if someone says that they would be happy if the camera currently in hand would be great if it was the last model ever available, then fine; we shouldn't automatically call BS just because the masses are likely to move in a different direction.
After all, this isn't a popularity contest, and really, in relation to the global population, anyone owning a camera/lens outfit that cost US$500 or more is operating in a niche sector already.
