USB4: Based on Thunderbolt 3. Two times the data rate, at 40Gbps. One fewer space. Zero confusing versions

What about power delivery?

And alternate mode?

Those are the things that turn USB3 from a minor annoyance ("my device is running at 5Gbps instead of 10gbps - must be a slow port") to a game of what will work with this usbc port.

I've recently shopped for a laptop dock, and half of them use the Alternate Mode to support at least one of their displays. Does the port on my laptop support HDMI alternate mode? Displayport? Neither? Neither. Great.

I've also been shopping for a new power adapter for my Nintendo Switch, which uses USB-C (ish, apparently). All I need is USBC PD, right? Nope, there are 4 different voltages and god only knows how many power ratings.

So much for the Universal part of the name...
