Thanks for the comment! A couple of things about this...

1. the Go team is working very hard to ensure that there are no such compatibility issues. Code written for Go 1.0 should still compile with Go 1.14 beta today.

2. It's possible there's more we could have done along the way, and I tend to think that statically typed languages make it easier to safely refactor more ruthlessly. But I do think we've actually done quite a bit of change incrementally along the way. Our move to React on the frontend and GraphQL on the backend have been good examples of that. Plus, we did a huge refactoring a couple of years ago to draw better boundaries in our monolith, and that has made a move to services possible.
