Bing AI Mode starts a separate baseline. Copilot remains a separate public engine and keeps its history; changes across the switch are not like-for-like growth.
How AI engines see them
All three engines agree that Nat Sakimura is a Japanese architect and author of digital identity standards and that he has chaired the OpenID Foundation since 2011. They credit him with OpenID Connect, JWT, OAuth PKCE and Financial-grade API. Google AI Mode adds roles the others do not, including chairman of MyData Japan, founder of NAT Consulting, and advisory positions at the Japan Fair Trade Commission, Authlete and PwC Japan Group. Every engine named the person, so none failed to recognize him. The engines cite sakimura.org and nat.sakimura.org most often, along with openid.net.
