@kentcdodds @reactjs oh no! I can stream it from from the US. Looks like there are some restrictions in some territories because of some music that was played during breaks, I'm working on fixing it

I was on the fence about RSC. I could see the new abilities it unlocked. But I was wary of the added complexity, and I felt like it wasn’t solving the problems that originally brought me to React. Seeing Parcel’s low level RSC APIs (and now @vitejs/plugin-rsc) changed my mind.
