Video Description

Cal Newport decodes the TikTok algorithm is episode 372 of the Deep Questions podcast. Buy Cal Newport's latest book, “Slow Productivity” at www.calnewport.com/slow Last week, it was announced that Oracle would take over operation of TikTok in the US. One of the primary reasons proposed for this deal is that it was in national interests for us to take over control of TikTok’s fabled “algorithm.” But what is this algorithm? How does it work? To what extent can it be controlled? In today’s episode, Cal looks deeper at these questions and arrives at a broader philosophical point about the role these services, in general, should play in our civic culture. He then answers listener questions on the same topic and reacts to the three recent news articles about TikTok’s influence on our culture.
