What next?

Sometimes this baby boomer can't sleep. I don't want to turn on the television, for fear it will keep me awake longer. I have noticed that I have a kind of "ipod" in my brain. I can recall tunes and play them for my amusment. Last night I was listening to some Copland from my brain, and I started thinking about how far technology has come in my lifetime. In the early 80's, when I was first a detective, we had to share a pager. The detective on call would keep the pager for that week. It was the size of a cigarette pack (one more thing to carry) and it would beep, signaling you to call the dispatcher. Of course you would have to find a pay phone - there were no cell phones back then. Before I retired, all the detectives had their own cell phones, and even the kind with that annoying two-way walkie-talkie. We got GPS's to follow the bad guys, and sometimes even to follow our own officers. We had body bugs and pin-hole cameras for undercover operations. We got in car cameras to record every traffic stop. Now there is a computer in every police car. This makes me wonder what will be invented in the next twenty years. I can only imagine that it will be something "in body", like my brain ipod. Maybe a forehead camera for police officers?
