It may happen for email and SQLite. Or at least a mail server that uses SQLite. In this July 2021 conversation Richard Hipp, the creator of SQLite, said he’s going to write his own email server: https://corecursive.com/066-sqlite-with-richard-hipp/ https://corecursive.com/066-sqlite-with-richard-hipp/ I’m going to write my own mail server. I was making notes on that even as we were setting up this call. That’s a big problem, and that’s at least as difficult if not more difficult than writing a database engine, but I don’t want to be beholden to Gmail. I don’t want them controlling my destiny. I don’t want them controlling the record of all of my conversations. I want to control that myself, and so I’m going to go through a lot of pain and a lot of work and a lot of effort to come up with some solution that I can control myself. I can go out and lease a virtual machine out there in the cloud and run it myself and not depend on a third party to control my email. I expect the foundation will be SQLite, just as it is for his source code control system Fossil.
