These days so much of our communication is done on a keyboard whether by email, Twitter or Whatsapp that we often get confused as to why someone is calling us when they could just text. Well now The Cosmopolitan Las Vegas has taken heed of this phenomenon by becoming the first hotel to have an AI-powered concierge. Amazingly they’ve also managed to give their chatbox some character (and a name – Rose) so she can have sassy conversations with you. Best of all she’s always there. Need more towels delivered to your room? Text Rose. Want only red coloured M&M’s at 4 a.m.? Text Rose.
