WhatsApp head Will Cathcart revealed that the app now has more than two billion active users; numbers were last released two years ago. Cathcart also emphasized that he will continue to defend the messaging app’s encryption, noting that, “for all of human history, people have been able to communicate privately with each other … and we don’t think that should go away in a modern society.” Facebook, which acquired WhatsApp for $21.8 billion, finds encryption a barrier to recuperating its investment.

Researchers at Microsoft Research Asia and the Harbin Institute of Technology have come up with a new technique to use artificial intelligence to generate live video captions. In the past, technologists have used encoder-decoder models, but didn’t model the interaction between videos and comments, resulting in mainly irrelevant comments. The new technique — based on a model that iteratively learns to capture the representations of audio, video and comments — outperforms current methods, according to the research team. Read more
