Humanity may split into two sub-species

Evolutionary theorist Oliver Curry of the London School of Economics expects a genetic upper class and a dim-witted underclass to emerge.
Spoiled by gadgets designed to meet their every need, they could come to resemble domesticated animals. Social skills, such as communicating and interacting with others, could be lost, along with emotions such as love, sympathy, trust and respect. People would become less able to care for others, or perform in teams.
