How do I avoid making assumptions about younger customers and AI?
Ice-T used his daughter's experience with phones to describe how familiar technology can feel different across generations. That personal example doesn't tell you what an age group believes about AI, so don't build a product decision on it. Ask people about the actual experience you're considering.

Someone who uses a digital tool every day may still want a person involved in an important purchase or a sensitive conversation. Ask what they'd want to control, what would make them uncomfortable and when they'd pick another option.
Watch how you phrase it. A question that makes one answer sound modern and the other outdated will get you the answer it hints at.
Compare responses within age groups as well as across them. The differences that matter often come from the task, the person's experience or the cost of a mistake. A small conversation can't become a generational rule.
Use what you learn to design choices. A clear way to decline a recommendation can do more for people than a campaign telling them the future has arrived. Familiarity is worth understanding, but it doesn't give permission.
