@foone For anyone wondering (like I was a while ago) why all the cool parallel interfaces went away and everything is serial now: Apparently the answer is crosstalk. 😔

The signals on the parallel wires interfere with each other at higher speeds and longer lengths, so it's faster and more practical to just send info serially.

@indigoparadox @foone That begs the question though: Why not switch to optical signaling?

The crosstalk issue is eliminated and the usable frequencies are *significantly* higher than those allowed by copper.

@indigoparadox @foone Well, the other main reason is practicability: a USB connector is simply so much easier to handle (and cheaper to make) than a connector the width of your phablet.

@indigoparadox @foone Also it gets really hard to keep the signals synchronized at high data rates and with long cables.

@indigoparadox @foone That, and matching the lengths (as required at high speeds) of many wires is no fun.
