There also is significant philosophical, ethical and religious opposition to transhumanism.Many thinkers from different disciplines and faith traditions worry that radical changes will lead to people who are no longer either physically or psychologically human.We are no longer living in a time when we can say we either want to enhance or we don’t.We are already living in an age of enhancement.Nicholas Agar, Victoria University

Even minor enhancements, critics say, may end up doing more harm than good.For instance, they contend, those with enhancements may lack empathy and compassion for those who have not chosen or cannot afford these new technologies.Indeed, they say, transhumanism could very well create an even wider gap between the haves and have-nots and lead to new kinds of exploitation or even slavery.Given that the science is still at a somewhat early stage, there has been little public discussion about the possible impacts of human enhancement on a practical level.But a new survey by Pew Research Center suggests wariness in the U.S. public about these emerging technologies.
