I do not think that there is any doubt that we will see more electronically assisted scopes in the future. Why? Because there is a market, and the systems are already being developed. When we as shooters go out and practice shooting at long ranges, practice reading the wind and using a reticle and mil dot master to accurately judge distance...well it is rewarding when we get it all right. It is neat to be able to do something that not everyone else on the block can do.
With that being said, there are people out there who would like to be able to go hunting the 1-4 times a year, but they do not want to spend the time shooting that some of us do. Some of these people have money, perhaps lots of it. Could they afford to learn how to shoot? Sure, but they have other things to spend their time on. So here, I have developed this Super Z3000 scope, all you have to do is put the dot on what you want to hit, hit a button, and it will take into account the 5 requirements of accurate predictive fires, and place a reticle in you view showing you exactly how to hit that target!
Now this Super Z3000 may cost 10-15k... but if you have more money than time....
So the people who are on this site may not be a target audience, but there is an audience out there who would pay for such a scope. So they will be developed.
As for electronics going down or not being reliable, for the most part much of that can be overcome. We have pieces of electronics mounted on the M777 that are very reliable, and they ride on the recoiling parts of the cannon. They take a very rough ride, but they rarely fail. I have never actually seen them fail come to think of it (not going to get into what they are or what they do).
Anyway, I am pretty sure that these "do it all" scopes will continue to be developed. And they will get lighter, smaller, faster and more reliable then they are now. It is just a matter of time. This does not mean that our simple mechanical scopes will go the way of the Dodo as simple will always have its place, but the electronics will come about even at a lower consumer level.
