OMG Cable - The New Batch Now in USB C, the implant is much smaller, but it’s even more powerful than before. Smartphone/tablet attacks, extreme long range triggers, geofencing, etc.

Thunderbolt is so cool to me. like. you're telling me this one cable is; charging my laptop at 90W, providing a 5k60 video output, using the 3 USB3 ports on the back of my display as a hub, receiving video from my display's webcam, and sending hi-res audio to my display.

First, USB-C is a specification for the physical connector. NOT the protocol. And it intentionally supports multiple protocols like USB, USB-PD, Thunderbolt, DisplayPort, HDMI, PCIe, etc. Some protocols exclusively use USB-c, like USB-4, Thunderbolt 3 & 4, USB-PD. 🧵2

And a lot of it has a belief that USB-C is somehow anti-Apple. Reality: Apple (& Intel) designed USB-C. The USB-Implementers Forum is responsible for USB-4, USB-PD, and many others. There are a lot of companies on the USB-IF, including Apple! 🧵4

Most people with wired CarPlay that switched from a lighting cable to usb-c will notice how much more fragile the connection is if using cheap cables. That’s because the moving parts went from the socket (lightning) to the cable (USB-C). So cable quality matters more. 🧵6

Correction: The idea that Apple/Intel invented C & gave it to USB-IF is based on an industry rumor citation. It’s believable with the timing & numerous similarities with Lightning, but only rumor. Apple is still on USB-IF, so trying to say C is anti-Apple is silly either way 🧵9
