Not a book, but I like to look at very niche reddit communities and imagine if their tech was adopted by the entire market. For example, years ago video game streamers were a thing, but a small niche was streaming "irl" - just walking down the street/etc. Now this is a huge section on twitch. A current example is vtubers (and hololive). Its just youtubers/streamers, but their using very sophisticated live motion capture, so instead of a video of a person you're watching a 3d real-time animated person. Body capture, face capture, advanced 3d modeling, etc. Take this niche and imagine it exists in the mainstream - does every person have a digital version of themselves? etc.
