The Optimists

The Optimists

l Ray Kurzweill Hans Moravecl Marvin Minskyl Alan Turing

Ray Kurzweil

l Author of “Age of Spiritual Machines: When Computers Exceed Human Intelligence”

l Robotics Engineer/Researcherl Precarn

Ray’s Ideas

l Historical Exponential Viewl Growth Fueled by Advances in Hardwarel Exponential Growth Persists through Paradigm

Shiftsl Next Paradigm: The Third Dimensionl The Software of Intelligence

Historical Exponential View

Growth Fueled by Advances in Hardware

l Faster hardware results in newer technologies

Exponential Growth Persists through Paradigm Shifts

l Moore’s Law will run out of steam in 20 years– No big deal – that paradigm will be replaced– Electromechanical Calculators, relay based

computers, vacuum tubes, discrete transistors and now integrated circuits

Next Paradigm: The Third Dimension

l Nano-tubes– 1inch cube is 1M times more powerful than human

brain

l Molecular computersl Electric Circuits

The Software of Intelligence

l Hardware no good w/o Softwarel Approximations to biological systems

– GA, Neural Nets

l Reverse Engineering of the human brain– Using nano-technology– Destructive scanning

Hans Moravec

l Author of “Robot: Mere Machine to Transcendent Mind”

l Robotics Engineer/Researcher

Hans’ Ideas

l MIPS vs Timel 1st Generation Universal Robots - 2010l 2nd Generation Universal Robots – 2020l 3rd Generation Universal Robots – 2030l 4th Generation Universal Robots – 2040l Life in the Short, Medium and Long Run

MIPS vs Time

1st Generation Universal Robots

l Year: 2010l Processing Power: 3000 MIPS (lizard)l General Purpose Perception, manipulation and

mobilityl Rigid Programming

2nd Generation Universal Robots

l Year: 2020l Processing Power: 100,000 MIPS (mouse)l Accommodation Learningl Adaptive Learning

3rd Generation Universal Robots

l Year: 2030l Processing Power: 3,000,000 MIPS (monkey)l World Modeling (simulations)l Learns from simulations when idle

4th Generation Universal Robots

l Year: 2040l Processing Power: 100,000,000 MIPS (human)l Reasoningl They will develop their own lives

Life in the Short, Medium and Long Run

l Short:– People use robots to do real work

l Medium: – Robots do all work, provide for humans

l Long:– Robots outgrow earth, reach into universe

Marvin Minsky

l Author:– Why People Think Computers Can’t– Will Robots Inherit the Earth?

l Robotics Engineer/Researcher

Marvin’s Ideas

l Webs of Meaningl Problem Solvingl Self-Awarenessl Knowledge and Common Sense

Webs of Meaning

l What is five?– Way to count– Std. Set of Five Things– Pentagon, x, v, cross

l When a meaning fails, switch to something elsel Don’t deal with things in a single way!

Problem Solving

l ‘do now’ programmingl ‘do if needed’ programmingl ‘do something sensible’ programming

Self-Awareness

l Are Robots Self-Aware?l Are Humans Self-Aware?

– What is going on in our minds?– Ears, eyes to strings of symbols

l What are the limits of Computers?l What are the limits of our minds?

Knowledge and Common Sense

l Computers– Get caught in endless loops– Interpret hyphen as minus– Send us bills for $0.00

l Common Sense vs Expertise (Complexity)– Kids playing with blocks vs solving calculus

problems

Alan Turing

l Turing Test for Thinking– Fool a human judge into thinking a computer is a

person via freewheeling conversation

l Objections– Machines have no soul– Humans don’t have mechanical reasoning– Computer do what we tell them– Analog vs Binary

The Pessimists

The Pessimists

l Ted Kacynskil Bill Joyl Kevin Kelly

Ted Kacynski

l Author of “Industrial Society and Its Future”

Ted’s Ideas

l Technology facilitates and consolidates centralized control

l As technology grows, we lose our freedoms and are forced to comply with the system

Bill Joy

l Founder of SUN

Bill’s Ideas

l New Technologies, New Challengesl Genetic Engineering and Nano-Technologyl Robotics

New Technologies, New Challenges

l Past:– Weapons– Developed by military– To be used once

l Future:– Nano-technology, genetic engineering, robotics– Developed by the commercial sector and military– Self-replication

Genetic Engineering, Nano-Technology and Robotics

l Specially engineered humans/machinesl Self-replicating nano-bots

– Can get out of control– Use Shields?

l Nano-bots lead to Robotics

Kevin Kelly

l Author of “Out of Control: The New Biology of Machines, Social Systems and the Economic World”

Kevin’s Ideas

l Will Robots Replace Humanity by 2100?– In nature, species rarely replace another species– Think of robots like children – let them go

The Realists

The Realists

l Ralph Merklel John Koza

Ralph Merkle

l Don’t block nano-tech research– We have to be educated in order to form an opinion– Tech. Advances could save lives– Economic Gain

John Koza

l 1GHz PIII does about 3000 MIPS– Where is the lizard?

Robotics Today

Discussion

Discussion Topics

l Where do you think we will be at in 20, 50, 100 years?

l Will Robots replace Humans?l Will Humans merge with Robots?

Ben Shahn

l Ever since I could remember, I’d wished I’d been lucky enough to be alive at a great time –when something big was going on, like a crucifixion. And suddenly I realized I was.
