More specifically by playing God in my comment meant the future may involve messing with our biology-biochemistry and things how they were intended to be by nature, and by doing so, we may be causing our own doom. Like for example, the 'gain of function' research, and the controversy surrounding that involved the possibility of creating a deadly virus from the lab. What's to say while trying to develop vaccines to certain diseases, we don't cause harm to other species, even our own.
