book review

This book tells a wonderful story about time travelers traveling through the future, shows the author's rich and bold imagination, brings wonderful and exciting space-time experience to readers, and also triggers a series of thoughts. In the future world described in the book, there are two kinds of human beings, namely, above and below the ground. This is just the aggravating version of the polarization of wealth and class in our society today. When time travelers travel farther into the future, they find that at that time, human beings have already been extinct. At that time, all of the planet made him feel sick and afraid. As the pioneer of travel novels, this book has sparked deep thinking about how humanity should develop in the future.Should we blindly innovate technology? Should we change our social structure? If there is a real crisis of racial extinction in the future, how can we avoid it? The time of human existence only accounts for a very short portion of the entire universe.If I have the opportunity to stand on the whole timeline and browse the world like a time traveler, I may deeply feel the insignificance and loneliness of being a human being.
