The impossible dream of USB-C
I think it is clear, the future is mostly wireless. Why would we need a Wired Connection?The only reason we need wired is either Power or High Speed Connection.Power: It is highly unlikely in the next 5 years time we wont have a true wireless power transfer,( i.e not sitting on a Power Mat ), enough energy to power a Laptop, Monitor or Desktop.High Speed: That is anything from Monitor Cable, Massive SSD external storage, External GPU, and.... I cant think of anything else. ( Suggestions Welcome. ) Basically, what Thunderbolt was designed for; External PCI-E and DisplayPort.Sometimes this year or next we are going to finalize what I hope will be the Wireless Standards for decades to come, 
802.11ax and 802.11ay.802.11 ax is the successor of 802.11ac, basically what the industry learned from LTE and LTE-A, and moves the best of those tech across to WiFI, works in both 2.4hGhz and 5Ghz. 
We could expect real world, uncontended speed of 1Gbps in 2x2, and 2Gbps in 4x4, and both are very conservative numbers.802.11 ay is successor of the failed 60Ghz 802.11ad. Real world speed 10Gbps+.Bluetooth 5 which and Improves version of 4.1. And Bluetooth 4.1 is the arguable first Bluetooth which really makes it acceptable in general usage, and if 5 improves the better.Assuming no Patents non-sense, we could expect to have WiFi chips in what we are connecting now via cables. You will only need cable for Power and High Speed Connection. And coincidentally Thunderbolt is going to be an Open Standard Next year.What we need to fix / improve is power delivery on USB 3.1 branding. May be Future revision of USB will do that. For now, sitting in a transition period between Wired and Wireless will always be a little painful in the short term.
