Lasers are getting 2x cheaper every 4 years and 2x more powerful every 5 years Inevitably they will replace all cartridge based ammunition

Haitz’s Law “... every decade, the cost per lumen (unit of useful light emitted) falls by a factor of 10, and the amount of light generated per LED package increases by a factor of 20, for a given wavelength (color) of light.” Found that writing about vertical farms. Hadn't considered lasers. Neat.
