First, Joanna tells David and Christopher about her experiment with an "ethical hacker" who got into as many of her webcams as he could-and the key insights she learned from him about staying safer online. Then reporter Betsy Morris joins the gang to explain how being more like Fortnite (and less like Facebook) has made Houseparty so popular with teens and young adults. Afterwards, Impossible Foods CEO Pat Brown tells David about how technology makes healthier, more ethical-yet still delicious-protein. David tasted the all-plant Impossible Burger 2.0 a month ago, and still can't get it off his mind.
