How can I talk about my value without pretending my job will stay the same?
A conversation about technology replacing familiar work can slide into a defense of a job title. Ice-T's discussion of music and acting points to a better question: which parts of the work matter enough to protect? Keep a record of your answer and bring it to role planning.

Take a recent assignment and separate the production steps from the decisions that needed your judgment. Count the relationship knowledge, context and responsibility involved, and don't claim that every step was uniquely human.
Then write down what you'd be willing to change. Maybe an initial comparison gets prepared a different way while you stay responsible for the recommendation. Maybe the administrative work shrinks and the conversation with a client stays with you.
Gather evidence of the contribution you want to keep: a corrected assumption, a resolved conflict, a choice that improved the result. Leave out any promise that an AI tool could never do something.
I'd bring this record into role planning and ask which responsibilities will grow, how success will be assessed and what training will support the transition. You're proposing a useful future role. Nobody's asking colleagues to pretend the tools haven't changed.
