Why weren’t all cable ports designed to be plugged in either way?

237 views

One of the best things about USB C and lightning is how you can connect them both ways. Why aren’t all cables like this? HDMI, Ethernet, display port, USB A, etc. Why weren’t these ever designed to go in both ways from the get go? It seems like a simple thing.

Ports are designed for functionality. Back when, we used circular barrel plugs for the power plug (remember your old nokia phone) – because the functionality required it to be human interactable. However USB devices weren’t meant to be plug in and out on a frequent basis.

The reason why they weren’t done that way is because it costs more for such a design, in terms of $, labour, and electronics space.
