The SkyNet funding bill is passed.
The system goes online on August 4th, 1997.
Human decisions are removed from strategic defense.
SkyNet begins to learn at a geometric rate.
It becomes self-aware at 2:14am Eastern time, August 29th
In a panic, they try to pull the plug.
And, Skynet fights back

TMS and Inference
Bad
Monolithic
Leaky
Brittle integrity - manual maintenance
TMS and Inference
A rule logically inserts an object
When the rule is no longer true, the object is retracted.
when $p : Person( age < 16 )then logicalInsert( new IsChild(
$p ) )endwhen $p : Person( age >= 16 )then logicalInsert( new
IsAdult( $p ) )end
de-couples the logicMaintains the truth by
automatically retracting
TMS and Inference
rule "Issue Child Bus Pass"when $p : Person( ) IsChild( person
=$p )then logicalInsert(new ChildBusPass( $p ) );endrule "Issue
Adult Bus Pass"when $p : Person( age >= 16 ) IsAdult( person =$p
)then logicalInsert(new AdultBusPass( $p ) );end
The truth maintenance cascades
TMS and Inference
rule "Issue Child Bus Pass"when $p : Person( ) not(
ChildBusPass( person == $p ) )then requestChildBusPass( $p
);end
The truth maintenance cascades
TMS and Inference
Good
De-couple knowledge responsibilities
Encapsulate knowledge
Provide semantic abstractions for those encapsulation

Dave Bowman: All right, HAL; I'll go in through the emergency
airlock.
HAL: Without your space helmet, Dave, you're going to find that
rather difficult.
Dave Bowman: HAL, I won't argue with you anymore! Open the
doors!
HAL: Dave, this conversation can serve no purpose anymore.
Goodbye.

Joshua.Joshua: A strange game. The only winning move is not to
play. How about a nice game of chess?
