I live and work in Silicon Valley. Everyone I know has a cell phone, and many people have more than one. I always wonder about etiquette: clearly, they should be turned off in meetings, and at public performances. But how about the people you see walking down the street and talking to a wire suspended in front of their throat?
We joke about it (”Remember when you used to be able to tell the homeless people from the engineers? They dressed the same, but the homeless people talked to themselves”) but this one of those questions that’s only going to get
thornier as we strap more and more pieces of equipment to our bodies.
Personally, I like to leave my cellphone at home.
