> The constant re-invention of databases/operating systems/virtual machines I wish that were the case but operating systems and systems software in general seems to be the most stagnant field. Everyone just buys the same FLOSS stack for $0 and compatibility is king, so there's very little research going in this field and much less of it ends up in any product you're ever going to see in use. I would love to see a vibrant scene of competing operating systems and databases with fresh new ideas and research.
