RANCHO PALOS VERDES—Google's Eric Schmidt offered little actual news at last night's All Things Digital D9 opening session, but as executive chairman of Google, what the 56-year-old industry veteran says matters.

Schmidt, who revealed he is writing a book on the nexus of technology and foreign policy, seemed truly concerned with privacy, Facebook, and spreading the word about the "Gang of Four." As one media colleague told me, he's a quote machine. I've collected what I think are the most interesting tidbits from the roughly one-hour session to try and figure out what they really mean.

1. Mobile Development:

"Eventually most development will be HTML5, but eventually is many years from now."

Google's lively Android app market is growing at a healthy clip, though it lags far behind Apple's App Store on the tablet side. Part of the holdup is that developers still can't build once and deliver on all platforms and most are still choosing to build for Apple's iOS platform first. A convergence on HTML5, which both Google and Apple support, could change things, but it won't come anytime soon.

2. Market Opportunities:

The largest market for growth "Mobile-Local-Social."

Sure it's an obvious statement, but when Google's leadership tells you this is where the opportunity is, you know they company will maintain a laser focus on all things mobile (Android), local (Places, Offers) and social (er…Buzz?).

3. What Google Told French President Nicolas Sarkozy at eG8:

"Don't mess with the Internet unless you really have to."

Calling the French leader a very colorful guy, Schmidt said Sarkozy talked about implications of technology on society and said for every revolution, there is a counter revolution. Schmidt apparently recommended that governments simply get out of the way.

4. YouTube:

"YouTube one of the most successful acquisitions in history of any company, mostly because of the scale it's delivering."

Is it just me, or does Schmidt sound a bit defensive here? YouTube is unquestionably huge, with millions of hours of video stored on its servers and thousands of hours of new content uploaded each day. However, the company appears to be going through a somewhat critical and, perhaps, painful transition from amateur video destination to a network-television competitor. Note that Schmidt did not mention YouTube's profitability.

5. On Google Wallet Outside the Android Ecosystem:

"[We have] no intent to favor just one platform "

Obviously this is clearest signal that Google's Wallet ambitions are bigger than the Android platform. The combination of an NFC, smart card/encryption reader chip and Google Wallet software could live on any mobile platform, but if, as Schmidt believes, other mobile competitors will offer their own wallet solutions, what chances are there that we'll ever see, say, a Windows Phone Google Wallet app?
