A Zippier Way to Share Big Files?

What good is a multi-gigabit transfer protocol when the flash memory which is used in most consumer electronics and it's memory interface controllers can't maintain the maximum theoretical nor attainable speed of USB 2.0 atm? Unless mobile phones will start coming with mSATA SSD's instead of the el'cheapo integrated flash memory ontop of an eMMC controller this technology is not useful at all. There are already plenty of "touch/kiss" based file transfer services which used BT and NFC and they never took off. Even Samsung gave up on it's "beam" tech, and yes although it used NFC with much lower bandwidth it was still enough for quick transfer of documents and general items between the phones, and on top of being easy to use Samsung had a large enough market share for it to be useful, however alas still no one used it. So yeah sorry i don't see how a technology which will require adding an additional radio to the already overloaded radio stack of the phone(AM/FM(US phones mostly), BT, GSM, NFC, WIFI), especially a proprietary chipset with a proprietary protocol will be a viable solution, especially when it's going to be hindered by the hardware (and software, i wan't to see Android or iOS handling gigabit speeds) of the devices themselves. If anything USB over NFC or something similar seems like a much better candidate for this type of technology most due to the backwards compatibility to existing hardware and software stacks and USB being more or less and open standard.

How often does this come up in consumer environments? 6 gpbs could be faster than the NAND flash, for both read and write. 4K video is only going to be 100mbps or maybe double that, for consumers.

I guess what I'm asking is what use cases do people see for this? The only time I can think of that it'd be convenient is backing up a device, but that also can be run overnight when the device is charging and bandwidth is plentiful.

Question is how close do these things need to be? From the looks of the video, it looks like two devices need to touch. Wires allow transfers even with distance between two objects, so does WiFi.
