At the end of April, a privacy expert and fellow at the Berkman Klein Center for Internet and Society at Harvard University told the media that his problem with contact-tracing applications was that “they have absolutely no value”.

Why then should Canadians be putting their privacy at risk if this is unproven technology that may not accomplish as much as people are saying?
Perhaps Eric from IBM could take a run at that.
