That written specification, for the system I work on, would be about the size of the novel "War and Peace."
Someone has to do the specifications, and it is best if a person versed in software engineering does it.
My understanding is that it is agreed upon that AI cannot absolutely replace human intelligence. At least not yet. We can’t presume it won’t eventually. I mean, it does know how to lie. :) Maybe it will go after your girl too. :)
But it reduces the work that you’ll have to do, which will reduce the number of people in your industry at the lower end where there is less creative work going on. The work that is basically drone work, it will learn to do.
You won’t have those thirty in your area doing checklists, because AI will be doing the checklists flawlessly, or flawlessly enough that one guy will be needed to double check everything.
It just cannot yet replace the higher end of the creativity ability in your industry.
