I can't wait for when wireless charging is able to extend multiple/hundreds of feet.

Wired drones are already capable of so much, and powering them wirelessly is going to be a civilizational game changer.

Edit: I'm talking high concept sci fi. The likes of which is probably outside of our reach but what we can strive towards. On par with Star Trek Transporters and Communicators from the 60s.

Wireless energy decays exponentially as distance increases. Wireless charging over hundreds of feet would require massive amounts of energy to the point it wouldn’t be worth it.

Technically it decays geometrically a distance squared.
