> 1. Does the Blitz RPC thing work the same way as TRPC?
Depends what you mean by "same way". Yes in that both provide fully typesafe client-server communication. No in that the Blitz implementation is a tiny fraction of the size and does not have any Typescript-related performance slowdown at scale like TRPC.
The Blitz RPC tech itself will scale forever. However as a company scales it'll probably face another problem which is API contracts between internal teams. When you hit that, you may want to adopt GraphQL.

Yep, I want Next.js to get off webpack too
