I am not saying AI's abilities are the shortcoming here. The problem is that people need to trust that software has certain attributes. For now, that requires someone with knowledge to be part of it. It's quite possible development becomes detached from human trust. As I said that would reduce the number of developers but the ones who are left would have to have deep knowledge to oversee it and even that may be gone. Whatever happens in the future, for now I think people will have to level up their knowledge/skills or get a new career and that's probably true for most professions.
