And that's why following the trail from the past up to the emergence of the modern technology that surrounds us in our daily lives, and affects our lives, is rather like a detective story. Because, at no time in the past, did anybody have anything to do with the business of inventing or changing things, ever know what the full effect of his actions would be. He just went ahead and did what he did for his own reasons, like we do. That's how change comes about. And it's like a detective story because if you follow the trail from the past up to a modern man-made object, the story is full of sudden twists and false clues and guesswork, and you never know where the story is heading until the very last minute.
