Transhumanism, the idea that humans should use science and technology to extend our natural abilities, is the religion of the 21st century. It's a concept that has been around since the 70s, but seems to be resonating with a growing number of people. Whether it's because of the rise of smartphones, the idea of the quantified self, disillusionment with the world, or something else, transhumanist ideas have been gaining traction in the last 10 years with no signs of stopping.
