Back when 5G cellular was first rolling out, a professor brought in a Qualcomm senior level manager and the topic was how 6G was being developed for long distance low latency capabilities.
How much of that was industry bullshit, no idea but it sounds like they had a pulse on the tech now that we hear about it years later.
It should be fairly intuitive. Sending electromagnetic radiation through copper or fiber will add physical distance versus a direct line of sight link. And the refractive index of light in the atmosphere is significantly lower, so the radiation actually propagates faster. Over long distances, those microseconds will add up.
The best example of this is the stock exchange in Chicago (and elsewhere) uses a low latency microwave link to save several milliseconds over the fiber links.

The lowest latency links right now are already wireless point to point links.
Says who?
My PhD in electrical engineering.
Care to elaborate or point to a reliable source?
