If we lived in a just, and virtuous world we'd all be using cheap coaxial cables with BNC connectors via whatever version of SDI is the highest bit rate.
Also, device manufacturers don't do SDI on consumer devices because SDI is by definition unencrypted and uncompressed, so it's at odds with HDCP.

Someone finally did what I've wanted to see for years: built a follow-focus unit that controls the focusing motors in the lenses, so you don't have to bolt a ridiculous contraption (and janky focusing-ring adapters) onto a lens to turn its (non-mechanical) focusing ring manually.
That FPGA should be powerful enough to do a lot of interesting things - anything from fooling around with commands (like with the Arduino board) to image manipulation (e.g. a watermark embed).
It's unsurprisingly annoying trying to compete with a bundle of cables using only one wire.
Btw DP cables are often twinax and eDP cables are often microcoax.
