I suspect this is a case of strong limitations in the medical establishment’s philosophy, causing legal issues and lack of motivation to research the subject seriously.
If we take this further—you’d expect more research into genetic engineering for a permanent abolishment of human suffering, since everybody wants to be happy, right? But I’m not familiar with any mainstream research on the subject.
I’m not sure of anything—just haven’t found much written material on the subject, so I’m trying to understand what’s going on. I suspect that:
(1): many people do not think about this from this perspective (and those who do may not believe it philosophically—eg. most people would see Brave New World as a dystopia)
(3): those who did try it encounter significant legal/cultural issues?
And in the (probable) case you’re right on that entire logic flow I would have expected A LOT more written material on the subject. What do you think?
