Search can cover other domains too... what about an AI that can search books/research articles/lectures/videos to diagnose a medical disease - some of which aren't actually published live to the internet (perhaps behind paywalls) -- then it takes a person's current symptoms and comes up with the best diagnoses from it's search across multiple media types. How about search in the context of AR... if people overlay data on top of the world we live in, in AR apps, will there be searchable things there? There's room for search related projects in the future, but it just matters what the data is, and why it's being searched. Normal search 'engines' for web documents --- that itself seems pretty much 'won' by google, until something better comes along (an implant that has better search than google, and I only need to think about what I want to search for then I automatically download the data to my brain for the top 10 results)
