I really don&#x27;t get the down voting: While we&#x27;ve come globally to the conclusion that we require signed software, curated app stores and kill switches for traditional applications, because sh#t happens, we&#x27;re going to distribute binary software in the browser without any such limitations? With the average user not even knowing that she is running some software from untrusted sources? (Yes, I know, it will be sandboxed, and there will never be a zero-day anymore in any browser ...)
