I don't think smart phones are conventional communications. The are smart. They are still the "tech of tomorrow".
Smart phones use conventional communications to do very clever things. But those clever things are range limited and require specialised equipment. They also have absolutely no "hackability" without specialised equipment (easy to get, sure... But still pretty much single purpose)
AM is literally a couple caps, inductors, resistors (edit: and diode) then an amplifier (a couple transistors and resistors). And the range of lower frequency radio waves is (or can be) phenomenal.
It's just that it takes some experience to operate on these frequencies, and their bandwidth is limited.
Smart phones do away with the experience requirements, and trade higher frequencies & higher data rates for range (and I guess trade digital encoding for simplicity)
I see parallels to software.
People are nervous to "side loading apps" on their phone, but have no issues downloading and installing an exe on windows.
Smart phones give you the "this is how" kind of experience, and abstract away the sheer amount of technology they leverage. Which is amazing, and is what makes them smart!
But the underlying technology is phenomenal. And I feel it's a shame that the majority of people don't have any understanding of "installing an app" or similar (like calling internet access "WiFi".... 2 distinct things!)
"Fragility" is the typical descriptor for this sort of thing. Advanced technology is very powerful, and that is obvious to see, but it also tends to fail readily without long-term planning, in disaster and war, of course, but also in more benign ways, like when a consumer becomes reliant on the technology for a way of life, and a corporation abused their unique ability to maintain the technology, and the consumer has no recourse.
