"Playing god" is a charge mostly levelled at development in technologies (e.g. gene editing, artificial "wombs" and the like) that modify humanity and nature. Futurists claim that humanity has already modified its surroundings. That we have become dependent on technology. And that technology modifying humanity itself in the future has been unavoidable. To someone who does not believe in a "god," what would "playing god" mean? And why shouldn't humans "play god"?
What philosophies argue against technologies and "playing god"?
