While I see Apple moving towards that direction, I don't know how it will play with things that DO need a connection: for example aux port in the car, or connecting a drone controller (these are two examples from my daily life, I'm pretty much sure there are many others)
The answer is Bluetooth dongles. I’ve got a Bluetooth to aux adapter in my car, and it works a treat. I much prefer it to when I had my (original) SE hooked up with a physical aux cord, since it doesn’t wear out from fiddling with it and it automatically turns on and connects when I start my car.
