I have a childhood friend who played as much on the computer as I did. He even wrote some simple games himself (as I did) but he is not a software developer now and I am. You can give hundred kids lego technic and most of them won't become engineers.
But some will. And not all those that play with them creatively will become engineers. Also, some kids who just consume iPad content will become programmers, but not because of the device. Some kid who never saw a computer before will also be men one.
Not everyone who is capable of becoming an engineer sees it as something they actually want to spend their lives doing but the skills children develop with toys like Technic are still valuable and have applications beyond just engineering.
