As someone who grew up tinkering with POV-Ray in DOS as a kid in the early 90s, and who ran out and bought an RTX 2080 as soon as they were available, I've always had a pretty good working knowledge of how ray tracing works. Given that, I absolutely understand how this functions, and in fact I've wondered myself if such a thing would be possible.

Of course, it's being funded by DARPA so at first it'll be used to kill "terrorists" around corners-- then the used equipment will pass down to the domestic police force and will be used for warrantless spying on innocent civilians. It's a cool technology for sure when taken in isolation! But like all new tech inventions, in today's hedonistic post-modern relativist consequentalist-driven society the potential for evil is greater than the potential for good.

Back to a topic from earlier today, I'm not the only one wondering not only which remote fringe holes these Democratic presidential contenders crawled out of, but how they've possibly gotten promoted to positions of actual power in society. To quote a video I once saw, "these people aren't great-- in fact, they're not even average." The Napoloean-attributed sentiment of "never interfering with an enemy while he's in the process of destroying himself" made me laugh too.
