Assuming you could concretely nail down all the vague terms you just used, I'd be willing to bet real money we won't have anything remotely like that within the next 10 years :)
I think a lot of people who suggest things like this use the image of a computer writing code, or generating code in a programming language that didn't exist, when I think in reality what's more likely to be implemented is something more like Automator for Mac OS: https://www.youtube.com/watch?v=Z56PBanBSx4
In Automator, pre-made blocks of code that do different things (filesystem manipulation, data transformations, application control, machine control) can be assembled into a workflow, and configured with options. It is possible that something like that could be given a speech-based UI (rather than keyboard and mouse) and the result is that pre-existing code is assembled and configured. That's a lot more realistic.
