How real is Second Life (SL)?
  • A motivating video

    (choose a scribe)

Virtual Forest Theatre
6
Exercise rules
  • Please follow all of the following rules
  • Do NOT tell anyone in SL your real name, or
    information that they may be able to use to guess
    who you are
  • Once we start, NO TALKING to people outside of
    your group

7
Step One UNC CH in SL
  • Follow these directions to find the UNC island
  • Start and login to SecondLife
  • Go to the Map (ctrlm)
  • Search for UNC CH
  • Wait for me (Bevo) by the Old Well
  • Take a seat while youre at it

8
Exploring UNC CH in SL
  • Spend a few minutes to orient yourself
  • Find 2 interesting things on the UNC SL campus
  • Not including South Building and Old Well
  • Write these down
  • How difficult was it to find? To navigate? Did
    they have real life equivalents?
  • Once youre done
  • Meet me in South Building discussion area (first
    room on the right)

9
Identity in SL
  • Your goal
  • Determine the identity of everyone else in the
    room
  • For each virtual person, write down who you think
    they are in real life
  • Remember Try not to give away your identity.
    Better yet, try to maintain a false persona if
    youd like.

10
Socializing and Collaboration
  • Did anyone grab scripts from Help Island?
  • Try to dance with others
  • Try out gestures
  • Create objects for others
  • Can you read the virtual whiteboard?

11
In SL Discussion
  • Briefly
  • Your rights as SL citizens
  • Acting ethically in SL

12
Wrapping up SL
  • Identity
  • Was it easy to determine who others were?
  • To disguise who you are?
  • Communication
  • Was it easy to chat?
  • What if a lot of people are chatting at once?
  • Collaboration
  • Was it easy to interact with others?
  • To personalize your interactions?

13
Wrapping up SL
  • Are you intrigued?
  • Would it be easy to get addicted?
  • Why?
  • What did you learn about SL?
  • Do you feel safe in SL?
  • Where did you feel you didnt have control?
  • Did you feel lost?
  • Can you learn any real world skills from SL?

14
Wrapping up SL
  • What determines peoples behavior in SL?
  • Do the same ethics of the real world apply?

15
Robots and AI
  • Robots
  • What are they?
  • What do you think of?
  • Examples?
  • A virtual, mechanical, or otherwise artificial
    agent
  • Are they intelligent?

16
AI Artificial Intelligence
  • John McCarthy (1955)
  • making a machine behave in ways that would be
    called intelligent if a human were so behaving

17
Strong vs. Weak AI
  • Strong AI
  • The ability to truly reason and solve problems
  • Will be it be human-like?
  • Weak AI
  • Appearance of intelligence, but cannot truly
    reason
  • Examples?
  • How can we distinguish between the two?
  • How can we recognize an AI then?

18
The Turing Test
  • Alan Turing Father of Modern Computing
    (1912-1954)
  • The Turing Test
  • Test the capability
  • of a machine
  • to demonstrate
  • thought

19
The Turing Test
  • General form
  • A human judge has a conservation with two others
  • A human
  • A computer
  • If the judge cannot reliably tell which is which,
    then the machine passes the test
  • Can you think of any limitations to this?
  • If a machine passes the test, is it a strong AI?

20
Chatterbots
  • Some attempts to pass the test
  • ALICE (Artificial Linguistic Internet Computer
    Entity)
  • Jabberwacky
  • What happens if they chat with each other?

21
Towards a Sentient AI
  • How far away are we?
  • Technological Singularity
  • A Smarter than human creation
  • Rapid technology acceleration
  • Beyond that which we are capable of understanding
  • If this is a reality, what does it infer about
    humanity?

22
Technological Singularity
23
Creating a Sentient AI?
  • Pros
  • Automation of tasks
  • More time for other activities
  • Cons
  • Too intelligent
  • Replace our jobs
  • Dangerous

24
Creating a Sentient AI?
  • Should we pursue building an AI?
  • Is it ethical to do this?
  • If so, what rights should they have?
  • Are they just property?
  • Can they be just turned off?
  • What should be the governments involvement?

25
Robo-ethics
  • What ethics should a robot have?
  • Isaac Asimov I, Robot
  • A robot may not injure a human being or, through
    inaction, allow a human being to come to harm.
  • A robot must obey orders given to it by human
    beings except where such orders would conflict
    with the First Law.
  • A robot must protect its own existence as long as
    such protection does not conflict with the First
    or Second Law.

26
Faults of the laws
  • Are these laws sufficient?
  • Robots unknowingly break one?
  • No single robot breaks a rule, but together they
    do
  • Understanding of the laws?
  • How would you change the laws?

27

  • Social Issues
  • Medicine and Access to Medical Information
  • In government E-voting and Public Information
    Online (if time allows)
  • Readings 34-35
