I think the issue comes down to the model we use to understand intelligence. Why for instance are we so intent on claiming that a human intelligence is 'one' designer.
Everybody has different characteristics and aspects that can be more or less present at different times. Our cells die and replenish over a period of years.
Is each individual 'one' designer?
I would say not - its just easier for us to think about people in that way!
just read this short ebook discussion of free-will and intelligence. its quite short and loosely based on David Hume's similarly titled piece.
Worth the read especially since its free at the moment.
