It looks like an alternative to Jsonnet which has schema validation & strict types. IMO, Jsonnet syntax is much simpler, it already has integration with IDEs such as VSCode and Intellij and it has enough traction already.
Cue seems like an e2e solution so it's not only an alternative to Jsonnet, it also removes the need of JSON Schema, OpenAPI, etc. so given that it's a 5 months old project, still has too much time to evolve and be mature.
We're heavily using Jsonnet for our data modeling (https://github.com/rakam-io/recipes) and pretty happy with it. We also have plans to add support for JSON Schema which is adopted by many of IDEs so that VSCode makes us feel like we're writing Java, not a Jsonnet file.
Cue is Google's 6th attempt and given that Jsonnet already has traction and works well out of the box, I would invest my time into Jsonnet at this time.
