For anyone who hasn't read it, see locating the hypothesis

Some of the predictions are affected by this more than others, but it's hard to judge in any case. For example, the "nanotechnology is prevalent" hypothesis wouldn't be that hard to locate, given that a lot of people were talking about nanotechnology at the time. Then it's just a matter of deciding yes or no based on evidence and your model(s). On the other hand, something like his prediction that "Personal computers with high resolution interface embedded in clothing and jewelry, networked in Body LAN’s," while wrong, is much harder to locate in the hypothesis space.
