Technology won't kill lying. Despite there are clear and distinct punishments in society for those who murder, people still don't resist their impulses or think they're can out smart the system (some do, some don't).
Technology will never stop those who have retaliatory power from lying. Janitor catches CEO lying about making a specific sales deal go through versus CEO catching janitor lying about when he clocked in. Strong intra-team asymmetries exist.
Technology could have killed lies long ago. It didn't. Why would it start now?
