Facebook had to shut down its chatbot experiment after two AIs (artificial intelligence) developed their own language to communicate. Researchers at the Facebook AI Research Lab (FAIR) were experimenting with teaching two chatbots, Alice and Bob, how to negotiate with one another. The researchers soon found that the chatbots had gone off script and were creating their own unique language without any human input.

Having abolished roaming charges in 50 destinations and introduced industry-leading care initiatives like TOBi the chatbot in April, Vodafone UK has made even more improvements that put customers' needs at the heart of its service including new AI digital customer service initiatives.
