Bezos is a billionaire who's marital status is single. When it comes to events you attend perhaps once in a lifetime and you get to meet all the ppl you wouldn't otherwise come across, it creates sparks/ friction that alters your life forever.
He may be been a genius in his field, but growing up, and later being successful in business, it's not usual for him to meet world dignitaries, royalties, and old wealth money folks, and enter a parallel universe where he's never got a glimpse of. I think after this event, and after meeting the wives of everyone else. He may possibly have a very different perspective about what he wants in his future wife. So Sanchez may have gotten a ring (I think she did), but he probably will think twice about marrying her.
