"The question now is whether governments can put the genie back in the bottle through concerted, co-ordinated action. Many politicians say the power to tinker with biology is too dangerous to have in the hands even just of doctors and must be regulated."
Similar arguments are being made regarding the public's access to general-purpose computing, 3D fabrication equipment, AI agents, and indeed: drugs (both psychoactive and medical). Putting this increasing number of "genies back in the bottle" is infeasible and I would argue harmful. We'll be putting an ever-growing amount of our civilization's resources into controlling technologies and behavior just so we can act as if it's still 1975, while unaccountable mega corporations reap all the benefits of modern technology.
I am utterly unconcerned by what people choose to do to their own bodies and minds. What does keep me up is the potential harm to bystanders, both in premeditated acts of terrorism as well as uncontained accidents. I really don't have an answer to this, but I do know that iron-fisted government control of citizen technology is not going to prevent these horror scenarios.
