That’s what I said.

Nextel iDEN is a good example of a hyper low-latency digital mode that could be used, although likely a CDMA-based air-path would be a better choice as all radios can talk on the same channel at the same time without interfering.

Would be a very complex system to make durable, but remotely possible.

Unlike digital modes with control channels and parity bits, it would be pure analog. Not impossible, but the glitches causing risk of a failed transmission are likely not worth it. If you listen to AM with squelch off, it is a swirl of signal and noise. DSPs could do some filtering, but again adding a big risk factor.

Say plane A backs off and retransmits right when plane B transmits for the first time and plane C is on a path to collide with A. C might still suffer the same fate.

There really isn’t a protocol. One can build an AM radio with a Zener diode and some common electronic parts.

Not trying to internet neg on the idea, to be clear. Just statistically, adding variables equally adds potential problems.

The radios aren’t even digital, or even FM. They are AM so multiple can talk at once. Such an entrenched technology that would take decades to replace across the planet. Buffering could reduce some cross talk, but at the expense of possibly dangerous delays.

Passable and stupid, just to work around their over-engineered walled garden full of overlapping security certificate messes. All controlled by Apple infrastructure.

Very far from genius.

Muskrat blows up 50 rockets for sport and puts air travel at risk for the lulz. SpaceX was initially interesting in that small vacuum of NASA activity, but nowhere in the same wheelhouse. All flash and no substance, like the rest of the tech bro industry.
