Thats not what I meant by interconnectedness, my mistake. What I meant is: having the same connectors on different devices. The issue solved is that nothing then has to become waste. If Apple decides to use a slightly different connector, and make their old one obsolete, then yes, it becomes waste. Of course technology evolves, but the usb-c standardisation is not meant to say "nobody can ever innovate", it just means that as long as it is in effect, predatory companies can no longer wall off themselves through non-sustainable, greedy business practices.

The "bit at the end" definitely is an issue though. Thats where the interconnectedness between devices can happen. If you have to have the same end on one side, but a different on the other, its the same as having completely different ones. The problem being solved, is that now ALL cables will be used for ALL devices, not just charging blocks.
