AI is useless.
If you think it can substitute designers.
It should be a complementary tool that expand our cognitive abilities, not something that prevent us from thinking in the first place. Here's my approach to AI.
In this example, I've asked ChatGPT what could have been added to the structured of a questionnaire I had thought for AVIS project.

To obtain a user persona, I write the information about the target audience from the research phase, such as interviews, surveys, or desk research.

This is an example of how I've used NotebookLM to test what I had designed for a fintech company as part of their hiring process. P.S.: if you find it too harsh on me, that's because I explicitly told it to be critical of my inputs to prevent it from only making compliments.
