RethinkDB, SageMath, Andreessen-Horowitz, Basecamp and Open Source Software
To understand what happened to RethinkDB, you want to contrast it with MongoDB.RethinkDB is amazing software and a real breakthrough. And the audience of deep thinking people who can really leverage the event model is ... limited. Today.MongoDB is no breakthrough, but there are legions of people who just want to plug something together with PHP or Node. Given what they're doing, it works fine.I sincerely hope Rethink can turn into a vibrant open source project and I'm willing to donate money to that. Given sufficient time, the world will learn to use it. And until then, it will grant superpowers to people willing to invest a little effort to understand and leverage it.
