There's an alternative like UWB in RF that caters for more bandwidth if needed but come with low power requirement across the wide bandwidth [1]. Or the the FCC/OFCOM/etc need to bite the bullet and provide huge chunk of RF spectrum for this next generation wireless peripheral standard that's comparable to USB 4. Together with the latest offering direct RF ADC/DAC and RFSoC it is just a matter of time for this realization [2],[3].

I believe the issues lamented by the grand parent comment is resolvable even in RF spectrum and the required speed will be achievable in the near future, stay tuned.
