I mean, REST-ful JSON APIs can be perfectly type-safe, if their developers actually take care to make them that way. And the self-descriptive nature of JSON is arguably a benefit in really large public-facing APIs. But yeah, gRPC forces a certain amount of type-safety and version control, and gRPC with protobuf is SUCH a pleasure to work with.
Give it time, though, it’s definitely gaining traction.
Satisfactory 1.0 releases tomorrow morning.
