Absolutely no. The idea of introducing one universal connector standard itself sounds reasonable but it still is a way ahead of time. Nothing should be "ditched" before the new standard and its ecosystem matures (do you remember for how long did USB co-exist with COM&LPT and for how long did ISA slots co-exist with PCI? - that was good!). Also one port is not enough, I want to connect my wired headphones and a power bank to my cellphone at the same time without using any additional dongles! And at last but not at least there are things tat are so good (with simplicity of their technology nature contributing to this) even while being a very old invention that inventing reasons to ditch them is either hypocrisy (aren't big corporations pushing digital audio transfer technologies just to facilitate vendor lock-ins and DRMs?) or onanism. Do we really need to reinvent a wheel just because it is not patented?
