Is there a place where the world can provide ideas on how to solve complex global issues? Something that that curated the best ideas, forms pros and cons to approaches proposed and automatic weighs the risks? I guess what I imagine is some sort of machine learning solution that takes in account the knowledge of the internet and allows for weighing of various factors based on assigned trust scores. It seems weird that we live in this information rich society, a ton of ideas float around the web but they are never acted upon or formulated in ways that harness public support. Am I just envisioning a utopian idea or is this possible to build? There Must be a way to pull most prominent ideas into one place for public scrutiny without creating additional noise.
