I wasn't saying physics has been completely already, only that it seems fairly easy to imagine a future point at which it becomes completed. Physics becomes "solved" as it were, much like checkers, and there's no more physics research to do, only problems of physics education, science communication etc remain. On the other hand, it's not at all obvious that we can easily imagine chemistry one day becoming "completed". Part of the reason is perhaps because the properties of compounds are not straightforwardly predictable from those of their constituents; chemistry remains heavy empirical, computation chemistry is never seen as a central branch of chemistry.
