Simple choices mean faster decisions and less possibility for error.

Computers can make only very 'stoopid' decisions between 2 things.

But this is a good thing...

Very complex things are built from many simple, carefully ordered decisions.

Which vegetables do you like on a pizza?

  1. Do you like pizza?
  2. Do you like vegetables on pizza?
  3. Peppers?
  4. Black Olives?
  5. Green Olives?
  6. Rutabaga?
  7. Mushrooms?
  8. BONUS QUESTION:  Are mushrooms your favorite?

The human judgement– and responsibility– is the programming of the questions, and dealing with the results.
