Liveblogger here. This post was best-effort liveblogged while the talk was going on, and this is an error transcribing the talk on my part. I've made a fix to remove this line since it's misleading. Sorry about that!
What's more likely: there is an error in transcribing or the developers of one of the worlds largest websites think the first RPC protocol was written in 2007 (over, say, REST, which their entire API is built on).
Done reading there.
Not sure if bad written or just not knowledgeable, please do your research.
