Is Futurama the Best Argument Against Transhumanism?

Transhumanism is a scientific philosophy that says technology will solve all our human biological constraints and that immortality is right around the corner (well not RIGHT around the corner, but WAYYY closer). They envision a world of endlessly euphoric robo-humans that represent the next step in evolution. And while this sounds super awesome, we had to ask, will this really make us happy?!
