It's astonishing what technology enables us to do. But it really becomes relevant to humans, when there are emotions involved. Email is just another form of a letter, more efficient and cheaper in handling. What really drives the success is the ability to send images, videos, and establishing a higher frequency of emotional interactions. Let's go further, email became chats, chats became facebook, facebook became whatsapp and whatsapp became snapchat. Why? Because each service enables people to send emotions quicker, easier and more emotional. Snapchat seemed to be the perfect emotions channel. Until we saw HUG. An app that is transmitting emotions by vibration pattern.
