Sounds like you got a bright child! I think one shouldn't stop a child from exploring many things like that. Not saying you are. I think it just means, that they have not yet found the thing that keeps them coming back for longer time, while they are learning many skills, that can be useful in the future.

Also being a generalist is OK.

Perhaps the best approach is to have conversation with the child, that furthers reflection/introspection. Basically giving the child the tools to notice such patterns themselves and make decisions based on their iwn insight.
