The death of emotions?

From an article about the death of the smart phone:  "The idea of man/machine fusion is a terrifying one, with science fiction writers, technologists, and philosophers alike having very good cause to ask what even makes us human in the first place."  How long until humanity decides that emotions aren't really an essential part of being human?  There seems to be a lot of people living without them already.  What if technology makes it possible to bypass our emotions and live entirely through our thoughts?  That's a horrifying idea, especially because so many people would want to do it.

More than emotion is required when defining us as humans, but without emotion it would be hard to still call us human.
