Touring cyclist: can I patch this with some duct tape and a radio antenna I ripped off a car?

There is electronic shifting over cable too. Electronic shifting in general is far better than cable both in terms of performance and maintenance.

It's much easier to maintain, as headsets have become integrated it's become harder and harder to work with anything that runs from the brake levers through the frame.

Not needing to route cables (or wires) along and/or through the bike frame is a huge improvement. Anecdotally, everyone I know that has adopted Di2 seems to love it. The cost of these systems is negligible for the type of buyer who is shopping for high-end groupsets.
I do love disc brakes though.

In terms of maintenance, most cyclists would benefit more from internal gear hubs and carbon belts. From a product development POV, seems better to make auto shifting IGHs. Indeed this is how share bikes are designed.
The casuals whose bikes haven't seen a wrench since they were assembled aren't buying wireless groupsets. For them: we're in agreement about belts and internally geared hubs.
Automatic shifting has yet to prove itself to be more than a curiosity. A 20-something year old Autobike came into the shop I was wrenching in. It still worked shockingly well for being covered in rust. In good shape it would be an entirely adequate solution, if only it solved a problem anyone had.
My money is on e-bikes entirely supplanting any demand there may have ever been for automatic shifting on a bicycle. The motors have enough oomph that they make a lot of shifts unnecessary if you're not looking to maximize speed/battery life/whatever.

Counterpoint - the benefits of wireless are there but the worry of your unit dying in the middle of a ride now replaces the concern of whether your derailleur is tuned and ready to go. It's easy for a shop to assemble, but now I'm worried about shorting the control unit of my di2 which would be a pricey fix. I have two bikes: one with and one without di2. Both work just as well and one costs much more. I do love disc…

#18There's no stepping on each others signal? Error-correction?
Garmin is ending ANT+ because it's not-encrypted and Europe won't allow that anymore but it would be fascinating to do an ANT+ capture next to a marathon of 50,000 people, how does it deal with all that signal noise (BLE is on same frequency)

In cycling looking good is half the battle. Eliminating all the cables (except brake lines) looks way cleaner and therefore faster and cooler.
