What a future that would be. I don’t have a lot of wires at home, but I get sick of the mess every now and then, and try all sorts of means to reorganise those wires, usually to no avail. Imagine the convenience of having every electrical appliance in your home powered without any restrictions on positioning. No more issues with different countries’ power outlets compatibility. No more worries about wires shorting, or outlets blowing, or anything like that.
I hope this can really take off in the future.
