Thanks for going through the extra effort of answering me again.
As for the Holodecks, I feel they touch more fiction in general, movies, games, etc. and I for one don't really feel them impacting books or literature any more then video games and movies do... However it did give me an idea for an additional scenario:
Visual novels will be implemented in AR and played with, for example, Google Glass.
What's your opinion on that?
And I would also like to ask for you to consider the first scenario again, this time leaving out the "audiobooks replacing traditional books" as I didn't realize people would get so caught up with that first point, and completely miss the second point of the scenario about "Interactive audiobooks, played with, for example Amazon Alexa." If you are still in the mood to answer again, I would like to know what you think about that specifically. (I did also edit it in my first post now, and in retrospect I don't know why I thought the first point was necessary to begin with.)
But thank you for answering once again, seriously!
