Thunderbolt on Pi
I saw this news and found it quite promising: https://www.phoronix.com/news/Arm-Thunderbolt-Works
If thunderbolt really works it could make a nice compact usbc connector that can carry the two HDMI signals of the pi and USB3 on one (fiber) cable over (large) distances.
I'm just waiting and praying for the day we see Thunderbolt/USB4 OTG. The amount of chaos a 40/80GB/s android or linux gadget device could do would be insane.
A USB 4 OTG Mass Storage + IP-KVM gadget would be an insanely destructive device.
I could just walk in to anywhere and take down an entire IT infrastructure down in seconds, by plugging into a USB 4 port.
Even if I can't find a USB 4 port, I could split the bandwidth and plug into multiple usb ports across several computers, and just force inject all sorts of malware.
I would pay money to have an engineer invent a USB 4 OTG/Dual-Role device that could take advantage of USB Gadget Mode on 80 GB/s of data.
The general term for a USB 3.x (and above) device controller is "XDCI" -- and if I search for USB4 xDCI, I see that Designware is apparently working on such a hardware IP. Good luck getting it in an actual device, though...
