It's very likely we'll hit a point where the connector (Type-C) doesn't change, but the cable standards do. Just like how USB Type-A has been very stable, or HDMI, DisplayPort and mini-DP. That said, I don't see USB Micro-B disappearing anytime soon. And everything USB power delivery is an improvement over how we used to do power via randomly-sized DC connectors. I remember spending quite awhile looking for alternative power adapters for my PSP-1000 which did have its own micro USB port. Don't get me started on proprietary cellphone power adapters... or the various 30-pin connectors ... https://en.wikipedia.org/wiki/Dock_connector https://en.wikipedia.org/wiki/Dock_connector
