The speaker challenges the common assumption in UX design that UX should be at the center of a company. They argue that this is a form of "navel gazing" and that it's time for UX designers to stop focusing on their own discipline and start collaborating with other teams, such as sales, marketing, and product management. The speaker believes that by doing so, UX designers can gain a more nuanced understanding of the company's goals and priorities, and develop solutions that are truly valuable to customers. They also note that many UX designers mistakenly believe they are the sole voice of the user, when in fact, everyone has a unique role to play in delivering value to customers. The speaker concludes by urging UX designers to stop navel-gazing and grow up, and to start collaborating with other teams to build great products.
