Iterating quickly. Basically you want to get something out there for people to comment on and play around with. But the engineering structure to get something out is not necessarily the structure to modify quickly.

I once launched a recipe app. People wanted diet recipes, so I added calorie data. Turns out diet was low carb and specifically they wanted a list of things below 5g carbs or so.

Then they hated the categorization UI. They were used to FB's style of having a wall, so they wanted cards and not a list.

They would add things to cart, but before making a purchase, they wanted to talk to a human on WhatsApp or something they could trace the number to. So I need to design the purchase flow with this in mind.

They wanted a community to support each other for dieting, so I gave them a single chat room lol. But massive public chat rooms are not a community, so we had to segment this into rooms.

You get the picture. AI is just great for these kinds of things but I feel like it's an incomplete solution.
