from a purely technical point of view i do wish HDMI 2.1 was able to gain traction. On a couple of things I own that do actually use it, its an actual noticeable improvement and I feel does a better job than DisplayPort.
Granted, I suspect quite strongly the next wave of consolidation is going to continue the trend of being around USB-C, since the spec should have the bandwidth to handle any video / audio protocols for quite some time. Matter of time until that happens IMO.
It also lets you have a single cord that could theoretically be your power cord and your A/V cord.
From a purely technical standpoint display port is a better standard. HDMI couldn't get their shit together to do anything with USBC and thus all USBC to HDMI converter cables run display port internally.
Display port already allows multiple video streams, ausiostreams ... Why do we need a closed standard to also do this?!?!
