Sure there is, AI Product Managers are the people who decide that you WILL see an AI summary at the top of Google Search results and you WILL like it and you WILL NOT turn it off under any circumstances.
This is a very bad article, probably to attract traffic to their PM course.
For me is very simple, there are AI Product Managers. But those are not PMS that use AI tools but rather those that manage AI products. And there is a difference between Software 1.0 and Software 2.0 (AI or ML model based) products. These products are not managed as engineering but science. These products are managed with experiments. These products are non-deterministic. These products have virtually infinite inputs and outputs. These products do not address one problem but many at the same time. So, if you ask me of course there is a thing such as AI Product Manager but not what the author, and many other PMs, think.
Product Managers really should have a solid grasp of the fundamentals of AI (gen and non-gen) as this will enable them to understand if it can add value to the software products they are envisaging. In the end it's another tool, be it a powerful one that comes with very specific challenges on UX side but it doesn't require a carve out of the PM role.
