Multiple tools from multiple people make it less likely that the entire ecosystem is going to collapse, but makes it likelier that any one tool will stop working. But that's not even my main problem. Integration is. Integration consolidates ideas in ways that can be packaged and spread to others, increasing the mind share of the paradigm. Unless a good solution is integrated, it will be the domain of a few hardcore adherents. Once an integrated solution appears, it will become resilient only by the virtue of being popular and cared about (I guess as long as it's free software). The flip side is that a modern web browser integrates so many things not core to any data management idea that few dare experiment with it. I'm curious about the Arc browser, but I won't bet my workflows on it unless it becomes open source.
