I think lasers are pretty wack when you think about them through this lens. A small, wand-like object in your hand can make light appear from seemingly nowhere. If it’s powerful enough it can set things on fire or blind people. Not to mention larger ones like laser cutters or the LLD, used to destroy missiles midflight. Thats sure to blow some feudal peasant minds
Yeah, a proof of concept is one thing, but scaling it up to deliver mega or gigawatts is a whole different beast. I’d be concerned about environmental impact with radio waves that strong.
