Isn't that what sw development today is? A description of a system and what we want it to do. With the advance of compilers, libraries, frameworks, linters, autocomplete systems and so on, we're already very close to describing the minimum amount of information the system needs in order to produce the correct result. To my knowledge actually physically writing the software has not been a bottleneck in a very, very long time.
Right now, it takes skill and labor to move descriptions between representations for business goals, engineering (where we have frameworks and linters, etc.), and external/customer facing documentation.
The customer is faced with an output from the design process. I think that we can turn that around now. Let customers edit part of the documentation, and let the AI adapt the system to their need.
