This speech offers a captivating journey through the history and future of gene editing, beginning with foundational discoveries in genetics by Darwin, Mendel, and Franklin, and culminating in the revolutionary CRISPR-Cas9 technology. It explains how CRISPR, inspired by bacterial immune systems, allows scientists to precisely edit DNA, opening doors to curing genetic diseases like sickle cell anemia and beta thalassemia. The speaker highlights real-world breakthroughs, such as the personalized treatment of Baby KJ, and envisions a future where gene editing could eliminate inherited disorders, extend lifespans, and even resurrect extinct species. Ultimately, the speech emphasizes that while gene editing holds immense promise, it also demands thoughtful ethical consideration to ensure equitable access and responsible use.
