Re: Err ..
According to rumors about Apple's wireless charger that has been delayed again, apparently it contains an A* SoC just like iPhones, Apple TVs and HomePod. There's no reason I can think of why you'd put something that powerful in a simple charging mat, so it is obviously something more.
Whether that "something more" is wireless power at a distance ala Energous, or some sort of very high speed near field communication that would obsolete the need for a physical port even for a connection as high bandwidth as 4K HDMI, who knows. It will be interesting to see what it is, and what it needs that computing power for.
