The Singularity?
The four assumptions of the Singularity
movement
1. Artificial Intelligence systems are
producing mindboggling results
2. Progress is accelerating like never before
3. For the first time we will have to deal with
super-human intelligence
4. For the first time we will have machines
that can do things that humans cannot do
22
23
The Singularity?
1
Artificial Intelligence systems are
producing mindboggling results
24
1. Reality Check
• The curse of Moore’s law
– The motivation to come up with creative ideas in
A.I. was due to slow, big and expensive machines.
– Brute force (100s of supercomputers running in
parallel) can find solutions using fairly dumb
techniques
– Moore’s Law is ending (Intel’s announcement
2016)
25
Reality Check
• Recognizing a cat is something that
any mouse can do (it took 16,000
computers working in parallel)
• It took 1.2 million human-tagged
images for Deep Learning to lower
the error rate in image recognition
• Voice recognition and handwriting
recognition still fail most of the time,
especially in everyday interactions
26
Reality Check
• DeepMind’s AlphaGo
– Supervised learning
– Large dataset of 150,000 games
– Monte Carlo tree search
– Reinforcement learning (playing against
itself)
27
Reality Check
• DeepMind’s AlphaGo
– What else can AlphaGo do besides playing
Go? Absolutely nothing.
– What else can you do besides playing Go?
– What AlphaGo did: it learned from Go
experts
– AlphaGo consumed 440,000 W to do just
one thing
– Your brain uses 20 W and does an infinite
number of things
28
Reality Check
• DeepMind’s AlphaGo
– Let both the human and AlphaGo run on
20 Watts and see who wins.
A 20 Watt machine of 1915
A 440,000 Watt machine of 2015
29
Reality Check
Supervised learning
• Learning by imitation
• Only as good as the expert that you
imitate
• The learned skills cannot be applied to
other fields
30
Reality Check
• Limitations of image recognition
– 2013 (Google + New York Univ + UC
Berkeley): tiny perturbations alter the way
a neural network classifies the image
The difference is invisible to humans, but enough to fool a neural network
31
Reality Check
• Structured Environment
– The more we structure the environment, the
easier for extremely dumb people and
machines to survive and thrive in it.
– What really "does it" is not the machine: it's
the structured environment
32
The Singularity?
2
Progress has never accelerated so much
3333
2. Accelerating progress?
• One century ago, within a relatively short period
of time, the world adopted:
– the car,
– the airplane,
– the telephone,
– the radio
– the record
– Cinema
• while at the same time science came up with
– Quantum Mechanics
– Relativity
3434
Accelerating progress?
• while at the same time the office was
revolutionized by
– cash registers,
– adding machines,
– typewriters
• while at the same time the home was
revolutionized by
– dishwasher,
– refrigerator,
– air conditioning
3535
Accelerating progress?
• while at the same time cities adopted high-rise
buildings
3636
Accelerating progress?
• There were only 5 radio stations in 1921 but
already 525 in 1923
• The USA produced 11,200 cars in 1903, but
already 1.5 million in 1916
• By 1917 a whopping 40% of households had a
telephone in the USA up from 5% in 1900.
• The Wright brothers flew the first plane in 1903:
during World War I (1915-18) more than 200,000
planes were built
37
The Singularity?
3
For the first time we’ll have to deal with
super-human intelligence
38
3. Non-human Intelligence
• Super-human intelligence has been around for a
long time: many animals have powers we don't
have
39
Non-human Intelligence
• Bats can avoid objects in absolute
darkness at impressive speeds
• Migratory animals can navigate vast
territories
• Birds are equipped with a sixth sense
for the Earth's magnetic field
• Some animals have the ability to
camouflage
• The best color vision is in birds, fish
and insects
• Many animals have night vision
• Animals can see, sniff and hear things
that we cannot
40
The Singularity?
4
For the first time we will soon have machines
that can do things that humans cannot do
41
4. Machine Intelligence
• We already built machines that can do
things that are impossible for humans:
– Telescopes and microscopes can see
things that humans cannot see
– We cannot do what light bulbs do
– We cannot touch the groove of a
rotating vinyl record and produce the
sound of an entire philharmonic
orchestra
42
Super-human Machine Intelligence
• The medieval clock could already do
something that no human can
possibly do: keeping time
• That’s why we have to ask “What
time is it?”
The Singularity?
• The four assumptions are dubious at best
43
44
Decelerating Human Intelligence?
Journalist: Are you afraid of Artificial
Intelligence?
Piero: I am afraid of Human Stupidity
45
The Turing Point
• The Turing Test was asking “when can machines be
said to be as intelligent as humans?”
• This “Turing point” can be achieved by
1. Making machines smarter, or
2. Making humans dumber
HOMO MACHINE

The near Future of
Artificial Intelligence
"The person who says it cannot be done should not
interrupt the person doing it" (Chinese proverb)
47
The near future…
• Today’s #1 application of A.I.: to make people buy
things that they don’t need
• Tomorrow’s #1 application of A.I.: to make people
buy things that they don’t need (and that sometimes
kill you)
Wei Zexi’s parents (2016)
48
The near future…
• Where A.I. is truly successful…
– "The best minds of my generation are thinking
about how to make people click ads" (former
Facebook research scientist Jeff Hammerbacher
in 2012)
– So far A.I. has not created better doctors or
engineers, but better salesmen
49
The near future
• Toys: many robots are an evolution of Pinocchio,
not of Shakey
50
The near future
• Service Robots
The near future
51
Knightscope's K5 robot
security guard at the Stanford
Shopping Center (2016)
Savioke's robot concierge Botlr

(2016)
Simbe's robot clerk Tally at a
Target store in San Francisco
(2016)
52
The near future
• A new class of appliances
Chef robot (2015)
BioBeats (2016): app
that takes data from
several wearables and
uses A.I. to deliver
health advice.
Smart Tissue Autonomous Robot
(Peter Kim , Washington, 2016)
53
The near future
• Robots for an aging society (social
companion robots)
54
The near future
• Robots for dangerous jobs (explosives, radioactive
areas, other planets)
55
A little later in time…
• Industry-specific virtual assistants
• Chatbots that replace search engines
• Face-reading algorithms: detecting human
emotion (eg Emotient)
56
A little later in time…
• Analysis of medical images: X-Rays,
MRIs, Computed Tomography (CT), etc
– Philips Health Care: 135 billion
medical images, 2 million new images
every week
– Helping radiology, cardiology and
oncology departments understand
images
57
A little later in time…
• Robots
– Knowledge sharing among machines (eg
Open Ease, RoboBrain)
– Robots that can turn high-level
descriptions into specific actions (eg
RoboHow)
– Learning from human demonstrations and
advice, not just by imitation (eg
RoboBrain)
58
A little later in time…
• Progress in fundamental A.I.
– Deep reinforcement learning (DeepMind,
Osaro)
– Common sense - knowledge-based
reasoning
• Doug Lenat’s Cyc (1984)
• Catherine Havasi’s Open Mind Common
Sense (1999)
• Google’s Knowledge Graph
• Microsoft’s Satori
59
The next breakthroughs
• Transfer learning: transfer knowledge across tasks
• Multitasking
• Adaptation
60
The next breakthrough
• Progress in fundamental A.I.
– Common sense
Children form a
human arrow to
direct a helicopter
towards the suspects
(Enland, April 2016)
61
Beware of…
• Machine Learning as a tool for better forecasting
• Driver-less cars = brain-less cars
• Smart appliances that try to understand your habits
and customize your experience
• Intelligent agents “who” sift through strategic
information
• Chatbots that try to be funny
• Cyber-attacks

Don’t be afraid of the robot
• AI systems "don't have the intentionality, really,
even of an insect“ (Rodney Brooks)
65
Don’t be afraid of the robot
• We need AI soon.
• The society of robots will create new jobs that
today we can’t even imagine.
• Who would have imagined that the same
technology that gave us computer automation
would create millions of jobs in mobile
communications?
66
Don’t be afraid of the robot
• Robots will create an even more complex
society in which human intelligence will be
even more important.
• The future always surprises us.
