    Can’t we, please, have just a fast com port with 5V? Everything else should be made programmatically, without touching the hardware. A cable should be just a cable. A few wires, nothing more.

      The article kinda addresses that:

      “In order to hit 80Gbps, passive cables (which are the cheap ones) are strictly limited to roughly 0.8 to 1m in length. That means if you need a 2m cable for your desk setup, you must buy a certified active USB 4 80Gbps cable, which contains a tiny signal boosting chip.”
