Is it possible to adapt the MacBook Pro's HDMI port for USB-C?

I know some people were excited about the HDMI port on the new MacBook Pros, but for me personally, it’s of little use, and I’d love to be able to use that port with USB-C devices.

Is there any way to do this, by chance? For example, are there HDMI to USB-C adapters? Do they work?

No. USB is “Universal Serial Bus” and is designed to basically support any device. HDMI is “High Definition Multimedia Interface” and is designed specifically to carry digital audio/video signals from a source to a display.

While you can get converters from USB on a computer to HDMI to drive a display, it is not possible to convert in the other direction.
