Nothing is, he's just trolling.

  I'm not actually. Open world semantics means that you can never assume that a fact that hasn't been explicitly given doesn't happen to be on some server that is just temporarily unreachable. If you combine this with a monotonic query language and inference engine, which never retracts facts, you get a GSet with pretty powerfull operations. You can even arbitrarily cache facts without worry of conflicts.
