I wish they actually standardised the USB-C with actual data transfer and charging protocols inside, not just the physical shape of the port. It's a total mess these days. Why PD and QC are even different protocols? Why there are USB 2.0, USB 3.0 and then there are 3.2 gen 1 and 3.2 gen 2? And what about Thunderbolt?

The first is half a gigabit, the second is 5Gbit, then 10 then 20.
