AI’s impact on the Product workflow

I know each company has always had their own Product workflow, but with the increased velocity brought with AI, the company I work with has been pushing for Designers and PM’s to code more.
It got me thinking whether this was really the best way to optimise or whether the other bottlenecks were were our resources should be focused.
So I started thinking about the whole Product Workflow. Should Product people still be in squads? Should Designers be delivering production code? or are they better delivering detailed Spec and coded Poc’s to be handed over to Engineer’s?
I don’t have an definitive answer, but I was wondering whether any of you had any experience to share on the subject that we can all learn from?
