The original hype was when they were in closed beta, which was way more than a year ago. Internet Archive[0] indicates they started promoting it as early as January 2013.
Things do move fast, but hype doesn't move that fast. The reason I'm cautious is that they were extremely hyped before being able to deliver any actual code developers could use and that in the time since the original announcement, well, all of the past two and a half years happened (e.g. React).
