If you can sync your phone over Wifi, stream to audio over Bluetooth, and reliably and quickly charge wirelessly, then you can remove the port altogether allowing for thinner, more robust, more water resistant designs. It's probably also cheaper to boot.
That's the wireless future that I imagine Apple was/maybe still is imagining.
-embedded camera into the screen
-embedded fingerprint sensor into the screen
-embedded speaker and micro into the screen
All of these also mean there wont be a top or bottom with the phone, it could be used in any direction.
Especially, having thinner designs is important to have thin foldable phones in the future.
(Apple’s wireless deploys replace the cable, but I assume they do not happen over the cloud — both devices are on the same local network. I haven’t checked the network traffic, but I’d be surprised if the broader internet is involved.)
