key insights    
-- Loosely coupled teams quickly evolved software polytechtures with varying interfaces, decoupling data acquisition from analysis to enable use of expertise
at a distance.
-- The U.S. Coast Guard developed software to aid search and rescue and is an
interesting potential research partner for computer scientists.

-- New open-source tools and research could help with group coordination, crowdsourced image acquisition, high volume image processing,
ocean drift modeling, and analysis of open-water satellite imagery.

   What Next?

       A Few Remaining Problems in Information Technology          

1.Devise an architecture that scales up by 10^6.

2.The Turing test: win the impersonation game 30% of the time.

a.3.Read and understand as well as a human.

b.4.Think and write as well as a human.

3.Hear as well as a person (native speaker): speech to text.

4.Speak as well as a person (native speaker): text to speech.

5.See as well as a person (recognize).

Illustrate as well as a person (done!) but virtual reality is still a major challenge.

6.Remember what is seen and heard and quickly return it on request.

7.Build a system that, given a text corpus, can answer questions about the text and summarize it as quickly and  precisely as a human expert.  Then add sounds: conversations, music. Then add images, pictures, art, movies.

8.Simulate being some other place as an observer (Tele-Past) and a participant (Tele-Present).

9.Build a system  used by millions of people each day but administered  by a ½ time person.

10.Do 15 and prove it only services authorized users.

11.Do 15 and prove it is almost always available: (out less than 1 second per 100 years).

12.Automatic Programming: Given a specification, build a  system that implements the spec. Prove that the implementation matches the spec. Do it better than a team of programmers.
