> Stuff like GRPC / GQL feels cool, but JSON still feels "closer to the wire" This is like comparing a Mustang engine to a racetrack. They're not even equivalent technologies. GRPC and GraphQL would equate to SOAP, REST or some other interface protocol. JSON equates to protobuf, XML or another transport format. Of those three options, I have no idea how JSON would be considered the "closest to the wire". Protobuf is definitely the lowest level, while XML and JSON are about equivalent in abstraction.
