Soooooooo, wtf is Hard Light exactly? Best friends brother used to DJ back in the late 90s and early 2000s. He had to use actual turntables, not "pads" and didn't have, "Hard Light," whatever the fuck that is. Also, my little brother bar 🍸 tended for over a decade so it's all triggering memory lane, 😆.
You could have just googled 'hard light technology': Hard light technology, a staple of science fiction, refers to manipulating light (photons) to behave like solid matter, creating tangible, load-bearing structures, tools, or weapons, often achieved by giving massless photons mass via complex fields or dense mediums, allowing them to interact with the physical world, much like the advanced Forerunner tech in Halo or the tools in games like Destiny.
