At some point, encryption may be become so wide spread as to make the current generation of scanners useless.
Will it be possible to break the encryption. Possibly, but will it be real time or legal. I seriously doubt either.
Currently, the Sheriffs and Fire department where I live is partially encrypted. It makes listening extremely frustrating. Fortunately there are enough other systems to allow for interesting listening. Were this not my home system, I would probably not scan it.
How far will encryption go? That is difficult to say. My county system (which includes sheriff, fire, schools, and such uses encryption sporadically on all talk groups). Will private business encrypt? If it becomes readily available and the costs make it worthwhile probably.
Will this happen anytime soon. Not within the next five years. The costs are just too prohibitve right now. But as older systems are retired, encryption will be an option to be considered in a replacement. And we all know how people like all the latest bells and whistles.
