Why shouldn't we? Security on the browser level is actually stricter than that at the OS level most of the time. Any app you download from any random place and run can access your webcam - but a webapp has to request it. I don't think the web makes Trojans or security flaws any more likely, it just changes where they sit. For the OS you've got buffer overflows which have been common for years and bash injection vulnerabilities. The issue is if someone can break out of the sandbox. I think it's perfectly acceptable to make a web technology that can be the OS. I don't see any reason that such progress should be halted. The browser was an application to view and consume content. Basically a book reader where you could access thousands of books just by putting in the right URL to the book. Now it's the same thing but for applications. For features, functionality. With the right standards it's cross-platform - write once run anywhere. With improving specs and browser vendors caring about speed and UX it can begin to reach the same speeds anything "native" could. I don't think the security risks outweigh the benefits, and even with those risks we can work hard to mitigate them.
