RPC as a concept has been around for a long time and just like the pendulum of a lot of things that come back around RPC as a concept is something that people are now talking a lot more about. Now that we have like server components inside of react it does feel like react is a bit of a taste maker here in terms of introducing some of these concepts to people that they might not have come across before. There is nothing in react for REST API or GraphQL API but there's talk of building stuff on top of server components for it.
