FWIW, my book "Rebel With A Cause: Mark Twain's Hidden Memoirs," a "biography masquerading as an autobiography" is written in Twain's style (as best as I could do). I doubt that any robot could be programmed to come closer. Full disclosure: I was a computer programmer for over 20 years. I know the limitations and the overwhelming complexity of such a task, and that all non-trivial software contains bugs (usually not just one or two, but an infestation just waiting to be poked so that they swarm out).
