Because those signals are really high-speed, and the protocols are really complicated. Doing the equivalent of "yank cable from PC 1, plug cable in PC 2" is just about doable at a reasonable price point. Anything more complicated either requires a bunch of expensive hard-to-source dedicated chips, or a bunch of hard-to-implement software solutions. Especially stuff like reliable keyboard-controlled switching or USB-C laptop connectivity is a nightmare. In practice this means you either have to give up on features, or let the price balloon to unacceptable levels. |
