Since 2019, the city of Vienna has supported marriage for all. To promote the progressive attitude of the "World's Smartest City" in preparation for EuroPride Vienna 2019 and to take a brave stand for gay marriage, the Wedding of Siri & Alexa – the world’s first A.I. marriage – was announced. With a customized Alexa skill, everyone could marry their own Siri and Alexa in support of gay marriage – even in countries where gay marriage is controversial or illegal.
