How Would You Usurp the Web Browser?
cyclomedia wonders: "I've been thinking about this for a while now, and a recent article posturing about Web 3.0 brought forward some other suggestions which basically boiled down to 'what should be next.' Everyone here knows that HTML, Javascript and HTTPRequest are not the tools for building feature-rich interactive networked applications, but that doesn't stop Google, Microsoft and others from trying their best to use them to build office suites and the like. As one project puts it: 'we need to replace the Document Browser with an Application Browser.' So, let's get the ball rolling with my question: What type of platform would you like to see delivering the 'true' Web 2.0 in the not too distant future?"
In other words... what might succeed at doing exactly what Java and Flash promised to do, but have failed?
You're signing out Flash too quickly. I'd say give it a chance. I mean Flash 9 and Flex 2 are out just couple of months ago and Adobe also donated their supposedly (for Flash haters) "crappy" Flash 9 JS engine to Firefox, which will replace SpiderMonkey in the near future.
Flash currently has the best ECMA4 implementation out there, and fastest. And it's available right now, today, on all browsers, on Windows, Mac and Linux.
