If by AI you mean artificial intelligence, then no - I agree it's pretty obvious Google is more into AI than Apple.

But if by AI you mean ambient intelligence (what I said) then wat. Siri was widely available before Google took steps in this direction. This is the opposite of what you've said, though Google Now has since surpassed Siri in performance. Moving it into the browser increases reach and more fully realises the vision of ambient intelligence.

Should I stop assuming people know what is meant by 'ambient intelligence?'
