Who is the No 1 UX designer in the world?

Could you please elaborate on what criteria are being used to determine who the number one UX designer in the world is? Is it based on their portfolio of work, their influence in the industry, or perhaps their recognition from awards and accolades? Additionally, is this a subjective opinion or is there a specific ranking system that has been established to make this determination? I'm curious to know more about the methodology behind identifying the top UX designer globally.
