Elon Musk said Twitter may launch encrypted private messaging on Wednesday, outlining plans to enhance the communication capabilities of the service. Encrypted messages mean only the sender and receiver can see them.
In theory, Twitter and Elon Musk will not be able to see or intercept direct messages between people. Elon Musk also said Twitter will soon add voice and video calls so users can "talk to people anywhere in the world" without giving them a phone number. (CNBC)
