WHAT ARE THE ADVANTAGES AND DISADVANTAGES OF USING RULE-BASED SYSTEMS
=====================================================================

Notes from last time

1. only as good as we can code the rules
2. need to put all the rules
3. rule base hard to expand/maintain/delete
4. can't explain its reasoning as well as a person can
5. inference speed
   - CPU time
   - time of interaction (e.g., number of questions asked)


Put a computer inside a car

   sensors: temperature, air intake, wipers (rain),
            distance, crash
 
   store code: temperature too high 
               put the reason for it

   information from other sensors
