“computer storage is usually not a sexy topic for consumers, ranking barely above lower-fat hot dogs or more-viscous motor oil.

Sure, storage capabilities expand by leaps every year. It's expected. Then the new software you buy sucks up all that extra space, so your computer still finds data at the speed that polar ice caps melt.”

Kevin Maney, ”You must remember this. But if you don't, your watch will.”USA TODAY, http://www.usatoday.com/life/cyber/ccarch/cckev044.htm

General Observations, Motivations

• “Software is a Mess”, Jim Gray(ACM Turing Award Database Work,BARC Director, Data Engineering papers) hardware and media doing fine

• Real Focus→→→→ Transparent Information Access

• Transparency, Change hard to sell• Non-Traditional Approaches Needed

(capacity 100x/decade, throughput 10x/decademust lead the target)

• Collaborations RequiredGroups must complement each other
