TIL that a USB-A connector is, for all practical purposes, a quantum object citation needed It isn't. But it sure behaves like one, collapsing into a definite orientation only after you've committed to the wrong one. : it exists in a superposition of “right way up” and “upside down” until the exact moment you try to plug it in, at which point it collapses into whichever state guarantees failure.

The USB Implementers Forum yes, that's a real organization The USB Implementers Forum is the industry group that actually maintains the USB spec. They gave us USB-C, which is reversible - proof they knew about the problem all along. designed the connector with a helpful little logo on top to indicate the correct orientation. This logo is purely decorative. It cannot be seen by the human eye under normal desk lighting, under a desk, or ever, because the port is always facing away from you, mounted on the back of a tower, three feet behind a tangle of other cables.
