People often think new technology replaces the old. In reality it rarely does. To Sid Mead’s point, the problem is that it arrives, but not all at once.
New technology has– to some extent– to be compatible with the past. So rather than replace it, it often lays over the old system and encapsulates it. In doing this, it has a firm foundation but it also means it inherits some of the characteristics of the old technology.
It’s exactly the same process with trees. Every year a ‘new’ tree encapsulates the old tree like an overcoat, yet it relies on the old tree to support this new layer. Every knot, branch and imperfection is reproduced by each successive layer.
