Rightly so. Whatever you have been fed previously by WHO about masks being ineffective was a lie.
Here’s the evidence collated by @naval https://twitter.com/naval/status/1241157415262814208?s=21 https://twitter.com/patphelan/status/1244010733714788352
And here is a list of resources outlining that masks do indeed work: https://docs.google.com/document/d/1HLrm0pqBN_5bdyysOeoOBX4pt4oFDBhsC_jpblXpNtQ/mobilebasic

Related, essentially: “We’ll change our recommendation once healthcare works have enough” https://twitter.com/chloesalsameda/status/1245033736275517440?s=21

Fascinating discussion on incentives by @Jason @chamath @DavidSacks - “Masks, little downside, a lot of potential upside, culture clash between those willing to iterate and those who pretend to be smart” Brilliant. https://open.spotify.com/episode/0N3XLMzahTFVSFiizqhC9n?si=UTlOSe04R6eMngJPtiogPg
