This is a talk from WordCamp Kansai 2016, with the following session description:
"What would we build if we were starting from scratch today, knowing all we’ve learned over the past 13 years of building WordPress?" At the beginning of 2014, the folks at Automattic asked themselves this question. The result is what now known as Calypso. It is not only a product combining some latest web technology, but also the demonstration of what we see as the future of WordPress.
In this session, we cover a brief history about the evolving of Calypso, how we chose our development stack, and what we learned from them.
