While it's not difficult to imagine scenarios where we create bioweapons of unprecedented ferocity, state actors have probably already done this to some degree.

While it's not difficult to imagine scenarios where we create bioweapons of unprecedented ferocity, state actors have probably already done this to some degree. I argue that outside of engineered diseases it's difficult to imagine existential risks that could be posed by genetic engineering. Except, of course, making a better human which would almost certainly and immediately pose an existential risk to old Homo sapiens sapiens.
