Dreamforce, the tech mega-conference organized by Salesforce, is set to begin this week in San Francisco, with an expected attendance of 43,000 people at Moscone Center. Participants from around the world, such as Gabriel Fuoco from Brazil, are already arriving for the event. This year’s conference will focus on artificial intelligence and promises three days of learning, networking, and entertainment. Despite concerns about crime, drugs, and homelessness in San Francisco, Mayor London Breed and other city and business leaders are taking steps to ensure the safety of attendees, including increased patrols. The economic impact of Dreamforce is estimated to be around $90 million for the local economy, benefiting industries such as hotels, restaurants, and transportation services. The event is seen as good preparation for the upcoming Asia-Pacific Economic Cooperation (APEC) global trade summit in November, which will provide another opportunity for San Francisco to showcase its offerings to the rest of the world.
