Anyone ever listen to the TED radio hour? They had a good program on the GNOME project yesterday morning. Gene modification, and DNA tracking.Encouraging and scary at the same time. Would you like to know any future problems of a medical nature ahead of time? Is DNA traceing legal? Is designing your fetus ethical? And who has access to this material? Then thetre was a segment on GPS. I'm too old for a lot of this stuff, but do have a navigator GPS in my vechicle.[barely know how to use it] Had one in my boat along with a good compass, fantastic gadgets.A couple of years ago I met a guy who was a true techie on the Cumberland river. He had a lap top working with a GPS somehow. He was going to explain it, and I told him its sorcery.They are close to commercially producing GPS dots. You can use them on personal items, never lose anything anything again. And folks are worried about phone taps.Then comes counter measures. Mind boggling stuff, and to believe some folks believe the world is less than 7000 years old.
