That's been a large part of my job at times - working with product stakeholders who give a high level requirements overview and then trying to figure out all the edge cases they didn't specify up front, so that my team could properly design and estimate the work to build the features.

So: yes, most companies already don't require people designing things to be able to fully spec every edge case in advance, without any dialogue.

The question is: can your job be automated in 50 years? Maybe it can. But the computer has a long way to go. I don't think we have enough evidence to give any estimate of when (if) that will happen.

Thats different. You're the one designing the system -- Exercising judgement about which mechanical rules to implement.
