As we meet at the end of this journey, and before you and I embark on separate paths, let us reflect on the overarching theme of this book. My sincere hope is that you have gained a deeper understanding and appreciation of genome editing. This technology holds the power to fundamentally change the world, perhaps in ways we cannot yet begin to comprehend. How exciting it is that you and I are both alive at this time, when we can attest to having witnessed the world before and after the advent of genome editing!
