Wired data transfers are becoming increasingly niche.

There's some speculation that Apple might move to Thunderbolt on future high end iPhones. There is a possibility that 20 gigabit - 40 gigabit connectivity could be Apple exclusive for a while.

Neither Qi nor MagSafe is about data transfers.

WiFi already handles data transfers and is constantly getting faster. My WiFi 6 mesh outperforms my CAT5 wiring in my house.

It's left me in a conundrum of running CAT7-8 in my walls, or just expecting WiFi 7-8 to be fast enough.

60 Ghz WiFi already exists for high speed data transfers over short distances in a true wireless manner. It wouldn't be hard to add this to a phone.

The main need for such high bandwidth is usually for large devices like monitors which aren't typically connected to phones.
