Q&A
What are the main challenges in using CRISPR technology for gene editing?
Delivering CRISPR systems to target cells, especially in the brain, and determining optimal edits for complex polygenic diseases are major hurdles. System size also limits delivery.
What are the ethical implications of gene editing, particularly concerning enhancement rather than disease treatment?
Potential societal stratification based on access, blurring lines between therapy and enhancement, and long-term consequences of altering the human genome are significant ethical concerns.
What is the potential timeline for widespread application of CRISPR technology in treating various diseases?
While used for some blood disorders, widespread application to other diseases, especially those affecting the brain, will likely take 5-10 years or more due to complexity, particularly with polygenic diseases.
How might gene editing impact our understanding of personal identity and human motivation?
Gene editing could fundamentally alter our understanding of personal identity and societal values, potentially diminishing the importance of physical attributes as status symbols.
Show Notes
You're defined in part by the genome you arrive with -- so what does it mean when you can edit it? What does this have to do with viruses, copy-pasting, and whether we will modify the story of our own species? Join Eagleman with guest Trevor Martin, CEO of Mammoth Biosciences, for this week's episode about the remarkable situation we find ourselves in, now that we know how to read and write our biological inheritance.
