Lighting plug was probably apples counter to that ungodly sin upto the tech universe. https://en.wikipedia.org/wiki/File:Connector_USB_3_IMGP6033_wp.jpg

Weird, I was thinking this morning about Machine Translation of books and anime and stuff and realized it was (poorly) making all languages the same and in effect was a tower of babel.
