What you don't see is the hundreds of people and countless hours of work that went into stuff like this. None of it is one person just showing up and making it happen. Everyone has their specific skill set and role in the project, no one knows everything. We see the result, but the day to day of this work would look mind numbingly boring to most people. It's not about geniuses having inspiration strike and figuring out something amazing, it's about months and years of staring at spreadsheets, analyzing data, fixing your mistakes, double checking, running the test again. It's about not giving up not being wicked smart, though the people working on it are definitely smart. Also this is the expected result. We were sure it fell down not up already, this was a confirmation of that.
