I think that if you have the skills to manage a software project of any complexity then you, alone can create what teams are doing today. I think AI can characterize proprietary data formats and assist by writing parsers, providing helpful error messages, and pointing out inconsistencies and gaps in the specification. AI can eliminate the need for so much workforce. Rather than training existing workers, it can become the existing workers. ChatGPT is already more competent than 1/2 of the workers at my last job. Case in point - two teams were independently assigned a particular upgrade task. Since the project managers used different terms they didn't realize they were doing double work. Large language models could already disambiguate that kind of thing way back then, it is only getting better.
