Parents often warn their kids that everything posted online is permanent and that there's no guarantee that data will remain private. It's good advice but can you actually explain that? What does it really mean when we hit "delete," empty the recycle bin, take down a single post, deactivate a social media account, or set a message to expire? Parents raising digital natives should understand what happens to our kids' data before there's a crisis with a picture, post, snap, or tweet. On this episode, Marc and David are joined by computer science professor Abigail Marsh who breaks down this topic for non-techies, highlighting what parents need to know to keep up with our kids.
