alt Hacker NewsAgree whole-heartedly. The strong contracts are the #1 reason to use GraphQL.
The other one I would mention is the ability to very easily reuse resolvers in composition, and even federate them. Something that can be very clunky to get right in REST APIs.

re:#1 Is there a meaningful difference between GraphQl and OpenAPI here?
Composed resolvers are the headache for most and not seen as a net benefit, you can have proxied (federated) subsets of routes in REST, that ain't hard at all

Contracts for data with OpenAPI or an RPC don't come with the overhead of making a resolver for infinite permutations while your apps probably need a few or perhaps one. Which is why REST and something for validation is enough for most and doesn't cost as much.
