FWIW jandrewrogers has a habit of making deep and well-informed posts that usually end by saying something like "this research area / idea was already conceived of by industry 10--20 years ago, but due to financial motives or secrecy we never published".

I hope jandrewrogers, who posts a ton on HN and makes what seem like high quality comments can start to provide some links / references to make them more useful.
