Biotechnologies in the context of "Playing God (ethics)"

Playing God refers to assuming powers of decision, intervention, or control metaphorically reserved to God. Acts described as playing God may include, for example, deciding who should live or die in a situation where not everyone can be saved, the use and development of biotechnologies such as synthetic biology, and in vitro fertilisation. Usually the expression is used pejoratively and to criticize or argue against the supposedly God-like actions.
