I think the question comes down to the fact they would have missed a great deal of education, both formal and informal. They would have a child’s understanding and the world but have societal expectations of an adult.

I think their outcome would depend entirely on how wealthy the family were. If it were a rich family you would hope they would employ tutors and the like to support building the formal education and have a great deal of empathy and support to help with, for example, the social understanding.

If it were a family without this kind of resource, I could see the person becoming a reality TV ‘star’ in order to pay for some of this, with an excruciating and crushing public interest.
