>OSS allows really hard pieces of software to be built

Like what that one couldn't build with proprietary software? The main benefit is with OSS you're doing it with free (as in beer) software (whereas before you might not afford a proprietary solution). But that is not a productivity increase, it's budget decrease.

>And what will happen with this technology if all the source code leaks somehow, don't you believe it will become 10x-100x better by some measures?

No.

This is benefit for user, but we were talking about benefits for someone who codes.

An OS which deserves to be trusted. Cryptocurrency. A web-browser which is not IE6. Lisp interpreter.
