Unfortunately, I am not able to predict what book reviews will look like in five years. The publishing industry and technology are constantly evolving, so it is difficult to say how book reviews will change over time. However, it is likely that online book reviews will continue to be popular, with platforms such as Goodreads and Amazon remaining important sources of reader feedback. Additionally, the rise of bookstagrammers and booktubers on social media may continue to shape the way books are reviewed and promoted. Overall, it is safe to say that book reviews will continue to play a significant role in helping readers discover new books and authors.
