• Tesla is never going to rival Apple or Microsoft as a "profit machine", according to Paul Krugman.
• It's impossible to establish an unchallenged monopoly in the car industry, the Nobel Prize-winning economist said.
• Tesla CEO Elon Musk has also destroyed his "image of cool" in recent months, Krugman added.
