During one of our coffee breaks members of the manufacturing team came to greet us.  Some of them spoke English, but most did not.  These are the people who make the devices by hand.  It’s tedious, careful work, in an environment who’s standards for cleanliness and quality are unlike anything I’ve seen.  If a pen falls on the ground it cannot be used.  They work for hours at a time, unable to even scratch their noses or adjust their eye glasses.  They work through microscopes in order to see the tiny wires and details of what they are putting together.  And if they are not careful, if there are mistakes, devices don’t work.  They are the ones who put amazing ideas into actual, usable technology.  Inventors invent, R&D develops, but without the careful work of that team, no one hears.
