This is so scattered… back on the semantics, I don’t think your buzzword is better than his buzzword.

Redux implements the Event Sourcing architectural pattern. So does: https://github.com/mobxjs/mobx-state-tree

And a host of other libs/frameworks/architectures. Knowingly or not, patterns will re-emerge if they fit a problem. It’s good that you’re bringing awareness, but it seems like you’re trying to impose some 1 buzzword rule. Architectures often start with or need a concrete implementation, Redux is both a library and architecture.
