Quote by David Deutsch
Time travel may be achieved one day, or it may not. But if it is, it should not require any fundamental change in world-view, at least for those who broadly share the world view I am presenting in this book.
Summary
This quote suggests that the possibility of time travel in the future should not contradict our current understanding of the world. The speaker believes that if time travel is achievable, it should align with their existing worldview, thus implying that it would not challenge any fundamental principles or concepts that we hold to be true. Therefore, according to the speaker's perspective, the concept of time travel, if ever realized, would not require a major shift in our understanding of reality.
