Objectively speaking, we have everything ready, and that is USB Type-C.

USB Type-C came out in 2014, referred to as USB-C, and appeared in the consumer digital field the following year. USB-IF sets USB-C as a future-oriented universal interface form. When USB4 is launched in 2019, it will no longer distinguish between different forms of interfaces (such as USB-A and USB-C), and only recognize USB-C.
