The whole nVidia 12pin kerfuffle made me question something else.
As we all know, USB-C fast charging pushes more and more watts. Also, we're using USB-C to even charge laptops. And the metal on metal contact inside the connectors for USB is incredibly thin compared to the 12VHPWR.
So the question is, how close are we to a similar scenario with USB charging? Could we see melting with a worn out USB-C laptop charger, for example?

Not yet, but how devices have pushed the USB-C connector to it's limit?
I do think I'm on to something though, as seen in the picture. The situation can probably be mitigated by having temperature sensors that slow down charging when things get too hot. But clearly there is a potential for problems, and USB standard will likely evolve to deliver even more power. A quick search reveals it's already planned to go from 100W to 240W delivery.
So it remains to be seen where the limit of the connector lies, since the connector itself will need to remain backwards compatible and likely unchanged.

@alyx I think USB-C is a much better connector in general. It's impossible to put it in wrong and most of the time it is a temporary affix, not one meant to be mostly permanent. You're only going to have a charger plugged in for a couple hours, and it's a pretty small connector so if it does get to the point where it could have an overheating issue it would most likely have slipped out by then, or the user would notice it not charging/not plugged in all the way since it is going to be on the side of their device in plain view, rather than inside a case surrounded by a bunch of other stuff.
