This is a big deal. I give the example of my mother making an international phone call when I was a child whenever I hear someone say there is no technological progress like there used to be. The whole process was quite a chore, and expensive. We had to go to the central post office in a big city, during working hours of course (through the snow, uphill both ways... just kidding). There was a special room with three phones on the wall and a person at the counter. We had to tell that person what country we wanted to call and what phone number. He then went into another room where he made the connection, probably with the help of overseas operators via some combination of undersea cables and satellites. When he made the connection he told us which phone to use. The call cost something like $10 per minute, which was a lot at that time, and the sound quality was poor. Literally every single part of that process has improved since then. Each improvement was small and incremental, barely noticeable, but together they changed the way we all communicate. I can now make a phone call to anywhere in the world for a few cents per minute, from something which fits in my pocket. That is amazing. I can't wait to see what incremental changes do to the way we drive cars in my lifetime.
