What
next?
World fastest computer?
200 petaflops, or 200,000 trillion
calculations per second
one petaflop is one quadrillion floating-point calculations per second
DoE and IBM Summit
The Internet cloud
More programs and data is stored on network
servers
The Personal Computer becomes one of the
form factors to access the network
Examples
Amazon API
Google Apps
Facework Platform API
The Network is the Computer
Tom Watson was wrong – there 

is not room for five computers.

It’s only one
The Network is the Computer
What about Moore’s Law?
Shift to multicore started in

2005 – new dimension
Move to cloud-core
Amazon has over 2.24
million machines in 

some 87 data centers
(2014 data)
Google has about 1
million
What about Moore’s Law?
USDbillions
$241
billion in
2020
33,000+ Data
Centers in the
world
Data Centers are

now a Software Problem
Small devices that have computer power
Wireless capabilities
Dedicated devices
Enough computer power for limited functionality
Examples
RFID
UAV – Unmanned Arial Vehicles
Internet of things
Medical - nano robots
Miniature Computers
How long will the Hard Disk Drive last?
Solid state memory is getting bigger
Terabit Flash Memory
Computer architecture will change
More and more devices are

using Flash memory
Driving prices down
The Future of the PC
New form factors
Wearables, flyables, drivables, scannables…
What is the future of Personal Computers?

Consumer Devices
Future of PC
Cloud Computing and home Serves
Everything will be connected: computer, TV, Phone, etc.
Simpler specialised operating systems
Utility computing
Wireless
Ubiquitous network access
Computers will be smaller and integrated into
things
New input methodsBetter interfaces
Big Brian, Small Brain
Better friction of devices
Consumer Devices
AI
Future of the Desktop Metaphor
Early Computers
Goal:
Data processing Read
data, process, write or
print
Early Computers
Result:
Dramatic Increase in
productivity
Automation
Xerox Early GUIs
Goal:
Emulate the
office environment
in a computer
Macintosh 1984
First commercial
GUI system
Macintosh 1984
Result:
More User Friendly
Graphics, fonts, WYSIWYG
Laserprinter
Windows 3.0
Business software
migrates to GUIs
Windows 95
First consumer targeted
OS
Windows 95
Result:
More people, connection

to the Internet
Ubuntu
Mac	OS	X	
Windows
More choices, less important
Android
Operating Systems Today
35
Is the desktop metaphor
dead?
36
Basically file systems
Concept of files, loading and saving
Multistep install process (parts made by lawyers)
Then with the Internet, the concepts of uploading and
downloading
These concepts are disappearing…
Traditional Operating Systems
38
Forgot to save
your file?
What do people do with computes? today?
Communication - talk, messages
Reading
Take/View Photos
Watch Movies
Shopping
Browse the Internet
Read news
Write documents, blogs
Financial transactions
Learning
Desktop, laptop, tablet, smartphone

Lots of devices - communicating
Less friction - just works
Simple and easy to use with

bad security

87% TV viewers are using a device when watching TV

The traditional TV model 

of scheduled TV does not

work anymore
The only thing that works in

TV is live TV and premieres

of major shows - due to Twitter
Digital World
Many objects around us will become

“smartobject”
Smart everything
Fitness trackers
Smart Leggings
Uses electrodes to 

monitor the electricity
in the muscles
Measure muscle
fatigue
New Reality
“I'm not crazy about reality, but it's still
the only place to get a decent meal.”

Augmented Reality
The blurring line between reality and virtual reality
Augmented Reality
Augmented reality (AR) is a direct or indirect live view of a
physical, real-world environment whose elements are
"augmented" by computer-generated perceptual information,
ideally across multiple sensory modalities, including visual,
auditory, haptic, somatosensory, and olfactory
Adding digital to the real world

How can Augmented Reality improve 

our life and work?

Facebook
What is the vision for Facebook of the Future?
Wearable Augmented Reality
69
Glasses
What happened to Google Glasses?
Product was primitive, low quality, very expensive
And not enough people wanted it, social issues
Marketing failure
Adjacent Possible
It was not the time - technology not ready
Will it come back?
Yes, in some form
Microsoft HoloLens
Hololens
Microsoft is targeting
enterprise users
Are not targeting the
consumer market yet
Price point needs to be
$200 for massive
consumer adoption to
be possible
Virtual Reality
Virtal Reality
Virtual reality (VR) is a computer-generated scenario that
simulates a realistic experience
The immersive environment can be similar to the real world in
order to create a lifelike experience grounded in reality or sci-fi
