Tech also seems quite vulnerable to monocultures. Think of file formats, for example. In the early days there are often several formats, but after a while most of them go extinct and the survivors end up being universally used. Image display formats, for example, fall largely into two categories - formats that every computer knows how to display, and formats that hardly anybody uses at all. (Image editing formats are different, I know.) How many word processors have you used recently that can't support .doc format ?

The most likely scenario is that there will be only one center of intelligence, and that although the intelligence isn't really there yet, the center is. You're using it now.
