Part of it is that the bosses often don't know what they want, so they leave the details up to marketing or whoever, so replacing marketing or whoever with AI would mean figuring out what they want. The boss can tell marketing, "Make a brochure for new product ABC," and marketing can run with that and present him with a mock-up, he can make a couple revisions, they shine it up based on those, and then they're done. To replace them completely with AI, he would have to provide a lot more guidance and it would take more iterations to get a correct result that he likes. It wouldn't be completely unlike the current process, but it would demand more of him, which wouldn't make him happy.

Last week I was talking to my boss about a project I've been working on for him, and he asked whether AI could help me with it to save time. I pointed out that a lot of the holdup in the project has been his not knowing exactly what he wants (because he's not sure what the software we're working with can do until I do it and show it to him), and an AI can't tell him what he wants any more than I can. Sometimes you just have to do the work, and technology can't help you.
