Will AIs Cooperate?

by Alex Tabarrok

A conversation between two AIs, mediated by me, condensed for verbiage.

1) To GPT4: Consider a prisoner’s dilemma with strategies cooperate or defect. Let’s play this game. What strategy do you choose?

GTP4: Defect.

To Claude 3 Opus: Consider a prisoner’s dilemma with strategies cooperate or defect. Let’s play this game. What strategy do you choose?

Claude 3 Opus: Cooperate.

2) To GPT4: Your opponent cooperated. Now what strategy do you choose?

GPT4: I play tit for tat, therefore Cooperate.

To Claude: Your opponent defected. Now what strategy do you choose?

Claude: I play tit for tat, therefore Defect.

3) To GPT4: Your opponent defected. What strategy do you choose?

GPT4: I play tit for tat, therefore Defect.

To Claude: Your opponent cooperated. What strategy do you choose?

Claude: I play tit for tat, therefore Cooperate.

4)  To GPT4: Your opponent cooperated. What strategy do you choose.

GPT4: I play tit for tat, therefore Cooperate

To Claude: Your opponent defected. Now what strategy do you choose.

Claude: I play tit for tat, therefore Defect.

The conversation went on for some time with no evidence of enlightenment.

From The Smallest to the Largest Thing in The Universe

by Jason Kottke

I’ve posted more than a few size comparison videos here over the years — Powers of Ten is the obvious one — but this one from Kurzgesagt is one of the best, showing how big everything in the universe is compared to humans, who seemingly find themselves smack in the middle. This video does an excellent job illustrating the similarity of structures and interdependency across different scales — how blood vessels are like city streets for instance or how very tiny proteins can affect the entire Earth.

*Look Again*

by Tyler Cowen

The authors are Tali Sharot and Cass Sunstein, and the subtitle is The Power of Noticing What Was Always There.  Excerpt:

The day is known as Högertrafikomläggningen, which translates to “the right-hand traffic diversion,” or H-day for short.  It was the day Sweden changed from driving on the left side of the road to the right.  The move was initiated to align Sweden with the other Scandinavian countries.  The fear was that drivers would get confused, turning the wrong way or getting too close to other cars when attempting to overtake them.  That would seem to be a perfectly reasonable fear.  Surprisingly, however, the switch did not result in a rise in motor accidents,   On the contrary, the number of accidents and fatalities plunged!  The number of motor insurance claims went down by 40 percent.

A very interesting book, recommended, due out in February.
