I agree with everything he said.
I am highly confident that Apple could update it to usb 3/thunderbold without changing the "lighting" connector.
Plus I also forsee people using the cable to sync to a computer less and less over the next 9 years. I personally haven't plugged my iPhone into my Mac since iOS 5 hit nearly a year ago.

Yes, the issue preventing USB 3/TBolt would be on the device side. The connector could stay the same.
If it adds no appreciable value then including it only adds cost and complexity. I'm glad they didn't bother with it. It's gimmicky.
I agree that NFC and wireless charging would have caused design compromises, but he didn't address that part, which is what I was poking at.
And wireless charging/power is the future. It's just a debate of when it arrives.
