When iPhone users ask, "Hey Siri, how do you start a conversation with someone who has a disability?" Siri gives the same answer she does in the public service announcement.
Cerebral Palsy Foundation CEO Robert Ellenson told Mic through a spokesman why Cook, Siri and Apple in general "were natural fits" for the campaign.
"Leading a world forward takes courage. Having a vision you insist on bringing to reality takes extraordinary determination and resilience. It's easy to think of Apple as the juggernaut it is today," Mic quoted Ellenson as saying. "But what's most compelling to me is the company's history and Tim [Cook]'s history. The unrelenting belief in a humanistic and accessible world that brings together a single person's individuality with a song of community and advancement."
