Comfort and discomfort aren't emotions. Pain isn't an emotion, and the absence of pain is desirable by people who don't have emotions.
But beyond that everything else is an emotion - happiness, sadness, anger, annoyance, loneliness. Beyond the most basic tasks everything requires emotions to drive you. Why do you study for an upcoming exam? Because you are anxious about getting a good grade? Why are you anxious? Because you may not want to upset your parents? Why does that bother you? You love them or fear their displeasure. Why do you fear your parent's displeasure? Ignoring corporal punishment (which could be an avoidance of pain/injury), other reasons include wanting to avoid stress, or being upset when they confront you about it. And so on. You cannot get through life except the most basic functions (like avoiding pain, eating, sleeping, etc) without emotions.
The article seems to equate the reduced perception of emotions to a total absence of them.
