I personally started coding at 8 with BASIC, using a book in another language (that I didn't speak) as a guide. This is the kind of thing a future programmer would do.
I tried teaching programming to my daughter when she was 8. We started with Python and it didn't go. I thought maybe we should try Scratch like everyone is telling us to do. It didn't go either because she was simply not interested in learning programming.
So a case study on a sample of 2 - does it count?
