Eh. What he has done is very impressive, but all of the produced books seem to follow an extremely similar tone; they are all technical works. Not that I am saying that technical writing is particularly easy (I am terrible at it, for example), however it does tend to be formulaic, which is perfect for a computer to generate. But there is currently no real creativity involved. It is certainly one aspect of the Muse. The ability to consume large databases of material and compound it all into a manageable and usable work. But it is perhaps the least technically difficult aspect, outside of its simple secretarial work. Your second example is simply an AI structure solving and playing a game. Travellers space battle rules are childs play for such a system. While I cannot wait for personal Muses, they would no doubt improve my life significantly (curse you, Dyspraxia!), I think we are a long, long, loooooong way off from anything that even closely resembles what the EP Muse is capable of.
