alt Hacker NewsThe problem with wireless energy is that the efficiency losses are mostly because of physics, not because of technology just needing to scale up a bit more.
A future with having wireless energy transfer everywhere is one where energy is so abundant that we don't mind throwing out 80% of it powering wireless things.
Ignoring efficiency, you can deal with "physics" by just eliminating matter in the way, like air, via a strong enough laser. I'm not sure I'd suggest this as a consumer product, though.
