Cable length is an issue. A fifty feet HDMI cable at Monoprice is less than 25 USD. A similar USB 3.0 cable needs to be active and costs 100 USD. My mind boggles at the thought of a 50ft USB C cable.

I can't imagine many people are buying fifty feet cables.

The only reason HDMI still exists over the vastly superior DisplayPort is the cable length. The DP standard, if memory serves, limits the cable to 3 metres / 10 feet so the max cheap passive cable you can buy on Amazon is obviously 15 feet. Meanwhile, the HDMI standard has no cable length limit but in practice 50 ft is the longest passive you can buy.

I'd say the only reason HDMI still exists is because everything has HDMI built in. The best standard doesn't always win, the most prolific one does.

When DP came out in 2008 it already supported 4K and HDMI didn't.

I don't see how that's in any way an argument against "the best standards don't always win".

Every conference room with a projector on the ceiling needs a long cable.

A USB Type-C to HDMI cable using HDMI alt mode works with a passive cable (and supports ARC, CEC, etc.), but is limited to HDMI 1.4b.

This discussion was about replacing HDMI with USB C -- I presumed on both ends. Switching USB C to HDMI alt mode and then running a HDMI cable is not replacing HDMI with USB C. Let's not even mention I am unaware of any product switching USB C to HDMI alt mode. All the available USB C to HDMI converters are using DisplayPort alt mode and an active converter, packed in one IC.

Good point, although I assume the price would fall in the coming years.

10gbps, 60W USB C-USB C cables are not even available at more than 6ft. It's too complicated a standard for that. You'd need fiber and USB-fiber extenders steadfastly refuse to come down in price even at 5gbps and I haven't even seen a 10/20gbps.

Interesting, I did not know it would be complicated.

USB C cables are built from micro coax assemblies https://cdn.shopify.com/s/files/1/1057/0966/files/JUCX01-Str... in order to make even this short distance viable.
