Kurzweil is pointing at the brain and saying "pattern recognition" the way someone might point at a car and say "combustion". He's asserting this is the core mechanism that makes it go. McGinn instead expects him explain all aspects of thought, including solving the mind-body problem. They are just on completely different pages. Kurzweil is off building a spaceship, McGinn is criticizing the cocktail napkin where he drew the plans.
