Choose wisely -- because once you pick one voice assistant, it'll be difficult to switch. As Scott Rosenberg writes at Backchannel, "If I want to switch assistants down the line, sure, I can just go out and buy another device. But that investment of time and personal data isn't so easy to replace... Right now, all these assistants behave like selfish employees who think they can protect their jobs by holding vital expertise or passwords close to their chests. Eventually , the data that runs the voice assistant business is going to have to be standardized."
