“False sense of security”—high tech gathering of 49 tech thinkers was held in 4 day “bubble” without mask mandate after arrival+daily testing. Result? ~43% (21 of 49) of tech attendees got #COVID19 soon after, including organizer @PeterDiamandis. 0% of masked support staff. 🧵 pic.twitter.com/EMziuecEJa
