"I bought it for $170.90 a share," Elias said, a small smile playing on his lips. "But more importantly, Maya, I bought a little bit of tomorrow."

Maya tapped her screen. "Well, right now, one share is trading for about $170. But that changes every minute."

He navigated to a brokerage site Maya had helped him set up. He saw the price flickering: $171.02... $170.85... $170.98.
