I struggled with this myself, the reality is that AI can automate the work of everyone in the traditional product team trio (pm, design, dev).

The way I have made peace with it in my mind is at the end of the day, I am the expert in UI/UX. There are many product teams I've joined that have operated without a designer and you can tell (bless their souls). Component libraries, templates, articles, video courses, and etc. have all existed throughout this time so it's not like they've been operating completely blind to design and UX. I don't think AI would be different. Sure it may raise the floor a little, but in the end someone needs to evaluate the output and hold responsibility for the UI/UX.

It was an uncomfortable idea to come to terms with though, I like many other designers spent a decade getting good at Figma. Figma and design almost felt intertwined for a moment, but designers have a long history of having their craft disrupted by new technology. Decades ago designers were cutting and pasting paper, then moved to digital publishing; and in product design we've gone through software such as Photoshop, Fireworks, Sketch, and Figma, just to name a few. Design has survived all this and will continue to survive in the future.

I think the same applies to the other disciplines. Sure I could have AI spin up a backend, but I don't really have the expertise to understand whether what it is doing is good or full of security vulnerabilities.

I don't know in the future if we will create a new path for product builders, individuals who are knowledgeable in all aspects of product management, software engineering, and product design. I also don't know if teams will have as much need for individuals with the efficiency gains from AI.
