Luke could only say, "You're not sensitive to technology, but for example, as long as Tony Stark wants to, he can make a product similar to our Titanium phone in a matter of minutes."
Jenny: "…Then why doesn't he?"
"Because he doesn't need to. He has so much science and technology in his head that can make a lot of money, and he won't be able to make them all a reality in his lifetime." Luke sighed again. "For example, it'll take nothing more than a bit of time for Stark Industries to replace Island Dragon, but he's not interested in doing something so boring. He's not interested in making phones either for the same reason. You don't have to worry about him stealing our livelihood."
The fact of the matter was that Tony's father had started out as an arms dealer. Although Tony was a playboy, he still valued family.
