Hi Sam,<p>I have a question relating to AI and YCR.<p>I remember your blog about AI mentioning how many of the best private companies are very secretive about their advances and research.<p>Was YCombinator Research heavily influenced by this secrecy in specifically the AI fields?<p>Is YCR going to have a focus on AI, at least initially?<p>Can you give any insight into the fields of research you are focusing on?
