In a world where this fake shit didn't take hold we could have had real wireless charging by now, if you think the "wireless" charging is good now, just think what true wireless would be like. You could walk into a room and your phone just starts charging with 0 effort. None.

You know this is possible how exactly? Wireless power distribution has been considered since Tesla's time. Yet it still hasn't been done outside of laboratory environments or very short distances. It's definitely possible, but making it practical might not even be possible within physics as we currently understand it.

For example a very power light beam like for example a laser beam can transfer a lot of power over some distance. It would also cook you, burn you, or make you go blind. It would also require precise alignment between transmitter and receiver, as well as very expensive transmission equipment.
