Ditching our bodies for bionic parts

Transhumanists Elon Musk and Zoltan Istvan this week announced that humanity’s future is to become computer-human symbiotes, or ditching our biology altogether for bionics and electronics. But their plans to eliminate hunger, disease, pain, and fear would also erase what makes us human—physically and spiritually.

Also: Musk announces plan to build city on Mars; Europa does cosmic spit-take; Swedish scientist editing DNA of healthy human embryos; disease outbreaks on the rise; three more priests killed last week in Mexico; and huge increase in demand for exorcists in America.
