Google spent Wednesday morning trying to get developers excited about the next generation of Web technologies by showing off how future Web applications will mimic desktop apps.

"It's time for us to take advantage of [this]. . .amazing opportunity," Google's Eric Schmidt told developers.

"It's time for us to take advantage of the amazing opportunity that is before us," said Google CEO Eric Schmidt, kicking off Google I/O 2009 in San Francisco. Schmidt was referring to the growing sense that the Internet and browsers--rather than a computer's operating system--will be the future foundation for application development.

The industry isn't quite ready for that yet. Many of applications demonstrated before the crowd of around 4,000 developers will require the widespread adoption of HTML 5 technologies, which are still under development by a consortium of companies and organizations.

Still, Google's Vic Gundotra, vice president of engineering, noted that the four modern open standards browsers (Firefox, Safari, Chrome,and Opera) are all adopting some HTML 5 technologies as they become more stable, taking every opportunity possible to ding Microsoft's Internet Explorer for lagging behind the other four browsers.

However, offstage after his keynote, Gundotra downplayed any conflict with Microsoft, noting that its task in moving toward HTML 5 is more complex because of the large number of enterprises running Internet Explorer, and the possibility that internal applications developed for that browser could break. "As they follow through, they are going to have a huge impact on moving the Web forward," he said.

Gundotra showed off how Web applications will be able to take advantage of five main HTML 5 concepts: canvas tags, video tags, geolocation, application caching and database, and Web Workers.
