The PRC (aka server functions) demo is particularly interesting — end-to-end typesafety (from DB to UI) is a major milestone for JavaScript.
We've been doing a lot of RPC design work in that space with Telefunc (tRPC alternative) [1] — we're looking forward to collaborating with the Void team. (Also looking forward to contributing as the creator of Vike [2].)
