Parenting: Aspirations for the Future

My 6 yo has told me over the course of time that when he grows up what he wants to be. It's been a truck driver, Jamie Oliver, a Pastor (after seeing one speak at an infant Baptism) , a Boxer but today it was an engineer. "Why?" I asked

"So I can build a big building that people can live in. It will be shaped like a T-Rex and people will sleep in its head. Then there wil be a slide that goes down through its tail and people will get out through a hole at the end of the tail".

I wonder if there will ever be a demand for T-Rex apartment buildings.
