I mean... if you really want those numeric ratings, I can really only rate them as follows, but I don't think they are the kinds of ratings you wanted.
1, 3, 5, 9, 10) 1; we already have this tech and these things haven't happened, I see no reason to think this will change
2, 6, 7, 8) 10; these have already happened, more or less
4) 3; if we forget about TTRPG comparisons and restrict this only to AI generation of content; it's an interesting question but I tend to doubt that AI will reach this point in my lifetime
11) 4; VNs may or may not become or remain the most popular, but they have plenty of room to become more popular
Though, I would like to point out that, you do, somewhat, seem to be underestimating the future (not like anyone expected the explosive popularity and addiction to social media, or Vine or TikTok, for example. FYI, I hate all three).
I'm not just speaking from curmudgeonly skepticism, though. I am quite confident, for example, that audio books will not replace printed books, because audio books have been around for a long time and that hasn't happened, nor come even close to happening. That doesn't mean that it can never happen, but it does mean that there's no reason to think that it will. It's just not really a relevant question to ask in this day and age.
The reason for grading is to not make them appear black or white, and to give some more easily digestible data for my thesis (every one to loves a good graph). The scenarios are extreme, simply because I'm not expecting any 10/10 grades.
Are they extreme, though? The only thing I really question "how" is around AI-powered storytelling; the real difficulty I'm having with most of these is not "how" but "why".
Consider the difference in asking whether we will ever have holodecks, and asking if holodecks will replace books. The former is purely speculative and maybe fun to think about, but the latter is a definite no, because why would they? Holodeck sims might eclipse novels in popularity, and perhaps it's likely that they would, but that's really all we can say. Even Picard was depicted reading books in his office on occasion, because Star Trek itself didn't envision one erasing the other.
