> Algorithms can and have been copied and improved.
Tiktok's algorithm can't be copied in the West. What makes it "so good" isn't some technical secret—it's that it starts apolitical and remains politically non-committal. If you're not into politics, it won't push political content at you. If you are, it won't suppress conservative views or force-feed you western progressive narratives. If you change your political interests it won't continue to nudge you towards western progressivism or Conservatism™ or some mainstream "safe" brand of political discourse.
Western corporations won't replicate this because they're committed to embedding specific messaging in everything at all times to astroturf and force national culture shifts.
This understanding is sufficient to explain the motive behind the Tiktok ban as well as why no extremely well funded and highly motivated, intelligent corporations in the west can repeat tiktok's algorithm success.
