Meantime, here is the sound-bite version of the IT trends articulated by the keynote presenters at the Gartner Symposium — from factoids that might come in handy at your next soiree, to pronouncements that might keep you up at night. About that latter category: Let me know what topics grab you, and we’ll do a “deep dive,” as they say on the conference circuit.

For your next cocktail party:

“It takes 10 years from early commercial availability to ubiquity.” (On the spread of the PC, the mobile phone and the World Wide Web)

“By 2012, it is estimated that the Internet will be 75 times larger than it was in 2002.”

“More video was uploaded onto YouTube in the past two months than all the new content ABC, CBS and NBC have been entering 24/7 since 1948.”

“Wikipedia launched in 2001. It now averages 4,300 new articles per day.”

“If Facebook were a country, it would be the third largest in the world, after China and India and before the U.S.”

“The computer in your cell phone today is a million times cheaper, 1,000 times more powerful and 100,000 times smaller than the one computer installed at MIT in 1965.”

“By 2016, one-third of mobile consumer marketing will be context-awareness based.”(For example, Starbucks sends you a coupon for a cup of coffee and tells you where to get off the highway, because it knows you’ve been driving for three hours.)

“Like it or not, we are on a one-way trip to the IT-driven intelligence society.”

To tell your CEO:

“Information is the oil of the 21st century.”

“In the next 20 years, Gartner believes there will be four trends that will alter IT, drive economic change and impact you. They will be cloud computing, social computing, context-aware computing and pattern-based strategy.”

“By 2016, all global companies will use cloud services.”

“Social computing — not Facebook or Twitter or LinkedIn, but the technologies and principles behind them — will be implemented across organizations and between organizations. It will unleash yet-to-be realized productivity growth.”

“Through 2015, pattern-seeking technology will be the fastest growing intelligence investment.”

“IT has helped companies to increase profits even with no growth.”

“65% of CEOs believe that information technology will make a greater strategic-value contribution in the next decade than in any previous period.”

Maybe not to tell your CEO:

“The rigid business processes that you have that dominate enterprises’ organizational architectures today are suited for routine, predictable business activities. But they are poorly suited to support people whose jobs require discovery, interpretation, negotiation and complex decision making.”

“By 2015, new revenue created each year by IT will determine the annual compensation for most global 2000 CIOs.”

In the not-too-distant future, “some CIOs will become CEOs of the Global 2000 companies.”

To ponder at 3 a.m.:

“The July 2010 CEO Confidence Index [from Chief Executive magazine] reported U.S. CEO confidence levels were down by 33%.”

“It is likely that most CIOs face another year of restraint, as most CEOs take a cautious view of investment.”

“The IT budget will not go up over the next few years. That means more and better services for the same dollars.”

“You’re going to have to decommission applications. Create specific decommissioning teams.”

“You’re going to have make better presentations before the board, the CFO and the CEO, because it’s all about economics.”

“You’re going to have to figure out which IT projects yield the best ROI.”

“You can save 50% of IT operational costs by moving commodity IT to the cloud. Use the savings to innovate.”

“Business is receptive to CIOs taking on new roles. Over 50% are taking on new roles.”

“Focus on outcomes, not output.”

“The world has changed, and you have to deal with it.”
