So, what ’s a “grand challenge”?

!I t is inarguably a signif icant research challenge – 5, 10, 15 years out !I t can be f ramed in a way t hat ’s inspiring not only t o comput er scient ist s, but also t o t he “general public” !I t s realizat ion would be widely recognized as a highly signif icant accomplishment – t o societ y, not j ust t o geeks

!I t was explicit ly a debugging run

"And t here were bugs!

!I t was f ocused on “syst ems”

"Alt hough t he at t endees included, e.g., Ron Brachman, Rod Br ooks, J im Foley, Tony Hoar e, Raj Reddy, Elliot Soloway, Andy van Dam)

!The goal was t o f rame some – not t he – “grand challenges”

"Absolut ely not “exclusionary” – on t he cont rary!

Mission St at ement

To save lives and minimize damage f rom disast ers t hrough t imely prevent ion, det ect ion, predict ion, and coordinat ion. Enabled by breakt hroughs in ubiquit ous sensing/ act uat ion, comput at ion, analysis and communicat ion syst ems.

A Teacher for Every Learner

Scalable Learner-Centered Systems

20-Year Vision

%Information Technology enables all learners

to participate in a network of communities, where they engage with other learners, mentors and teachers in self-expression, exploration, and learning by discovery and by doing

%The learning environment continuously

assesses and adapts to each learner’s needs

The Social Challenge

%Create a universally well-educated citizenry

that can adapt to a changing, global society

& For economic growth & For social and personal well-being & US international leadership in education

%Greatly enhance all learners’ abilities to learn,

and enjoyment of learning, over their lifetime

& All levels of learners & Customization for learner’s needs & Learning to learn

Mission

Informed by advances in learning sciences, pedagogical design, and assessment theory, lower the effective student-teacher ratio to 1:1 by building the technological infrastructure to support dynamic, ad-hoc communities of lifelong learners who interact within an environment of learning objects through a creative blend of advanced computing technologies, high performance networks, authoring and collaboration tools.

Enhancing Individual Productivity and Capability

Mission Statement

Increase individual productivity and capability through cognitive assistance

Strategy

!Augment every individual with teams of

Agents and Robots

"Agents: Cognitive programs "Robots: Cognitive machines

!These teams of People, Agents, and

Robots complement, assist, mentor, and monitor each other while collaborating together towards shared goals

Conquering Complexit y

Building Syst ems wit h Billions of Part s

J une 25, 2002

Mission St at ement

To ref ormulat e comput ing syst ems archit ect ures at all levels (f rom circuit s t o global-scale dist ribut ed syst ems) t hat break t hrough t he complexit y wall t o deliver robust , scalable, long-last ing, syst ems.

Why?

• We need comput ing syst ems t hat are t he

agent of change in societ y rat her t hat enemy

• f change
• Ever y ar t if act we build or grow in t he f ut ur e

will likely have a comput ing component

• We have run int o a complexit y wall, t hat limit s

and inhibit s growt h in business and societ al syst ems Tomorrow’s comput ing syst ems cannot be built using met hods of t oday.

Two Themes

1) Complex organized behavior out of many simple unreliable component s 2) Make complex syst ems simple t o t he

– User – Administ rat or – Designer

Addit ional mat erial

!A clear st at ement of t he pervasive role

• f comput er science in t he world of

t oday and t omorrow !The “base case” – where we are headed based upon predict able development init iat ives building on research t hat has already t aken place
