Interesting that what comes with disassembly is standardization, and performance is no longer a main differentiator. In addition to the UI/UX features emphasized in the post, ecosystem integration will also be a main differentiating factor. A data stack with a stronger developer community is more likely to be integrated, thus having better connectivity. The community also helps it quickly adapt to new requirements, facebook's TAO (graph db over MySQL) and most recently pgvector are good examples.
