Re: The future is called Powerpoint
There are many different techniques that would allow for more secure applications - i.e. getting rid of flat address spaces, and enforcing more control on different applications "segments" depending on what they are for (code, static data, variable data). Just that would create incompatibilities.
The idea that web applications are more secure than native ones is quite stupid though.... just like Java, the Javascript engines becomes just another vulnerable layer - as a large number of vulnerabilities in browsers had already shown - and the more those layers need to be integrated with the OS to allow the user perform useful tasks, the larger the attack surface becomes.
Unless they think about "thin clients" again....
