You're right. It's not very useful if you're just using it for pubsub. Go Micro was always intended as a full fledged framework for distributed systems development and you'll find if you build systems at scale you end up developing a similar framework in house. For those just using messaging or a database my advise would be to go directly to that system. Abstractions are only useful when they work together collectively for the foundation of something more. In our case when everyone is building Micro services we can actually run these absolutely anywhere regardless infrastructure and share them with anyone as a reusable building block.
