Thank you for sharing your perspective. I understand your concern about the potential overcomplication of UX design and the saturation of artifacts in the industry. It's true that simplicity is crucial in designing user experiences, and unnecessary complexities can hinder rather than enhance the design process.

While I appreciate your emphasis on focusing on users and creating user groups, the concept of anti-personas aims to complement these efforts rather than add unnecessary complexity. Anti-personas help to identify and understand the users who may not benefit from a product or service. By acknowledging and addressing potential pain points for non-users, designers can refine their approach and better tailor experiences to their target audience.

The goal isn't to create personas for everyone, but rather to refine the understanding of who the product is not for. This can streamline efforts, ensuring that resources are directed toward features and design elements that truly resonate with the intended user base. It's a strategic tool to help designers make informed decisions and prioritize aspects of the user experience that matter most.

Ultimately, the inclusion of anti-personas is not about adding more artifacts for their own sake but about refining the design process to deliver more targeted and effective solutions. I respect your perspective, and if you have alternative approaches or suggestions, I'd be interested in hearing them.
