What happened to dockport

A couple years ago I seen dock port and was uninterested. Running multiple devices over one cable was useless to me I could route cables easy and it was a non issue.

I have been working at a school for 2 years now and have to deal with labs of computers. Now I wish it caught on. Dealing with mouse, keyboard, monitor, speakers, and power cables is a pain in the ass when you have to run and manage 30 of them at a time. I wish i had one cable from my pc to monitor witch had all the usb, audio, and power.

Did dock port die and could all these be accomplished by usb type c in a way with minimal drives/software.
