In product design, Personas are a way to agree on jobs to be done, scope the work and help find new ideas for features.

In Marketing it helps to brief agencies and to talk about a big group of people in a less homogeneous way.

One person can be in multiple persona categories, and personas can change or evolve over time.

I don’t see the “dystopian” aspect in it, nor do Insee it demolish any idea.

It’s just a tool.
