Ask HN: Share Cool Ideas

Ever think of a cool idea but you either don't have the time or the energy to build it? Or maybe there's no money in it. There's lots of nice solutions to problems that are very hard to monetize. For example I got pissed off playing ping-pong because some guy was either consciously or unconsciously stealing points by saying a serve was illegal when it wasn't and I jokingly said I'll film it next time so there's no more argument. Then I thought about it and wouldn't it be cool to automatically film a friendly game and automatically cut clips of each point with some ML magic? Could also auto-referee small tournaments or something. You get the idea, share ideas you had that you think would be nice if someone else would build it.
