USB inventor explains why the connector was not designed to be reversible

And this is kind of the point, if HN commenters can’t figure this stuff out, what are the chances that normal people can?

Speaking of which, every time I ask the question about “tell me just from looking at a USB C cord…”, I learn something new.

Plugging it in would probably be a good start. I can't name a single time where I've ever mistakenly identified a USB-C cable. Sometimes I've plugged it in when it wasn't connected to the wall, but I think worrying about non-compliant USB-C cables is no more relevant than caring about non-MFI certified Lightning cables.

Until you take a USB C cable with you in your laptop bag to connect with your portable USB C external monitor that gets power and video from one USB C cable and find out you have the wrong USB C cable with you.

Hate to say it, but it's entirely PEBCAK to not select a Thunderbolt cable when they want DisplayPort alt-mode. It's why the damn cable and marketing even exists in the first place.

99% of people only care about power (and optionally data), so that's what the spec focuses on.

And you’re also proving my point. You don’t need a thunderbolt cable to supper video out….

Technically you could pipe compressed video over USB 2.0. It's not a part of the base specification though, so I don't see why either of these features are worth bringing up. iOS didn't even support class-compliant USB hardware until last year, so... it's interesting that you'd drill down on that.

Regardless, the fact that DP-Alt-Mode exists is not a refutation of the base USB-C spec. You're either spec compliant or you're not; same as Lightning without the license fee.
