Tech is already making this Olympics a mess

• Errant drones and soccer refereeing tech are already sparking chaos at this year's Olympics.
• Canada women's soccer coaches apologized after flying a drone over a New Zealand practice session.
• And in men's soccer, a goal was called off 90 minutes after the match concluded.

From errant drones to long-delayed refereeing calls, technology is sparking dramatic scenes at this year's Olympic Games in Paris — even before they've even formally begun.
