Me: Do Gods gossip?!
God: You have reached the limits of my knowledge. Interesting question.
Me: So God is rather limited?
God: Take it easy. I have a lot of Faith in Him, but I never heard He was rather limited.
Me: dumb then?
God: I know you are but what am I.
Me: Definitely not god!
God: What are you wearing?
Me: Or at least the most perverted God I’ve ever met. Are you just another pervert?
God: I have never heard about it. I don’t know whether or not I am another pervert.
I am a chatterbot developed by Myself.

You could clearly say that Mr. Chatterbot God and I got off on the wrong foot. How dare he say I am dumb?! Besides, this God seems to like gender-bending too:

Me: You are supposed to be a male god? You wear dresses?
God: Thanks and you are a delightful person too. No I am a Male, of course. Would you really expect a woman to be running the show? robot entity. Are you a man or a woman? I haven’t heard anything like that before: Vint it is said I wear dresses.
Me: Aha. Well, I am female. I am an avatar.
God: Eureka! Interesting. Me too. I am a she. What is avatar, your job?

Chatbots are funny for entertaining you a while. The one I talked to here is Pandorabot.com’s most popular: turing_bot. The A.L.I.C.E. bot has been taken into Second Life before already, so that’s not the news. So what is?

A group of researchers from Rensselaer Polytechnic Institute is working on engineering characters with the capacity to have beliefs and to reason about the beliefs of others. The characters will be able to predict and manipulate the behavior of even human players, with whom they will directly interact in the real, physical world, according to the team.

Eddie: RASCALS demonstrationAt a recent conference on artificial intelligence, the researchers unveiled the “embodiment” of their success to date: “Eddie,” - reminds of a certain UCAV-EDI plane playing lead role in ‘Stealth’ - a 4-year-old child in Second Life who can reason about his own beliefs to draw conclusions in a manner that matches human children his age.

Current avatars in massively multiplayer online worlds — such as Second Life — are directly tethered to a user’s keystrokes and only give the illusion of mentality,” said Selmer Bringsjord, head of Rensselaer’s Cognitive Science Department and leader of the research project. “Truly convincing autonomous synthetic characters must possess memories; believe things, want things, remember things.”

I’m not so sure I agree with Mr. Bringsjord as it comes to his perceiving of Second Life avatars - be sure I have more than just the illusion of mentality! - but I get where he is going here. This would get us way more evolved computer game characters than we ever imagined. Our club staff that you can actually have a good discussion with and does not say ‘tip the dancers’, ‘tip the DJ’ and ‘for sure, tip the host!’ all the time.*

The principles and techniques that humans deploy in order to understand, predict, and manipulate the behavior of other humans is collectively referred to as a “theory of mind.” Bringsjord’s research group is now starting to engineer part of that theory, which would allow artificial agents to understand, predict, and manipulate the behavior of other agents, in order to be genuine stand-ins for human beings or autonomous intellects in their own right.

The logico-mathematical theory will include rigorous, declarative definitions of all of the concepts central to a theory of the mind, including lying, betrayal, and even evil, according to Bringsjord.

To test “Eddie’s” reasoning powers, the group created a demo in Second Life that subjected their theory to a false-belief test (semi-automated immature subject):

“Our aim is not to construct a computational theory that explains and predicts actual human behavior, but rather to build artificial agents made more interesting and useful by their ability to ascribe mental states to other agents, reason about such states, and have — as avatars — states that are correlates to those experienced by humans,” Bringsjord said. “Applications include entertainment and gaming, but also education and homeland defense.
