Apples to oranges, very different characteristics. WiGig (802.11ad)'s up in the 60GHz band where even the oxygen in the air is absorptive, I think most walls pose big problems. But there's 6 channels of bandwidth each with 2160 MHz of space. Wifi by compare recently went from 480 MHz of space (5GHz) to 1600 MHz (+6E spectrum) of space available in total. Colossal gain, nearly tripled in bandwidth. But there's still less bandwidth in all wifi than there is in a single wigig channel. That wifi is making such excellent use of such a relatively limited amount of spectrum is amazing. I'm expecting impressive connectivity even at significantly reduced link budgets. But as for the point here, about interesting new inter-device connectivity, I agree with both of you. Wigig did have these capabilities, has had interesting video & device shipping for a while now. Alas adoption has been just critically low. VR was basically the only thing that pulled this impressive wigig standard out of the hole it had crawled in to die. No one was building this stuff. Huge loss, huge pity. I really wish we had a lot more experience using wigig like technologies, because to the grandparent posters point, having this massive connectivity capability on tap for everyday consumer & business wifi: it's definitely going to enable intense new streaming & inter-system capabilities. I just wish we'd gotten more of a chance to explore this space more freely in the past 10 years, which is about how long 802.11ad/wigig's been around for.

Sure the concept has been around, but not widely implemented. I participated in a WiGig laptop dock PoC a few years ago - it wasn’t great. Usually throwing more bandwidth at stuff helps.
