Well, we've somewhat reached a point where that connector will suffice. Today you can easily support 40+ gigabits/ second of data transfer which includes the capability for high-refresh rate, high-resolution, displays. All while supporting over 200W of power delivery.

Now, you device today might not support that. But you can, today, with some types of USB-C.

Its hard to come up with something better at this point. The connector is small, bidirectional, and strong.
