> We need an OS that controls the entire machine, and defends itself completely from applications. Until we have that, nobody is going to want your new app. I can think of one thing like this, the web browser! Sure it isn't a OS, but damn it can run one.
So you'd be willing to open any random website on the internet? I don't trust any browser that much. I never worried about the shareware disks and my PC, ever.
Frankly, yeah. Like yes, zero day vulnerabilities exist, and things can sometimes escape the sandbox. But I don't think a sandboxed OS will be free from them either.
