The artificial intelligence in the TikTok algorithm, Chang said, has allowed China to control public opinion. "It knows what you want, and it also knows what you don’t want," he said.

Does anyone actually know how social media algorithms work? And, more importantly, is there a way to "game" them to see more of the content you want? Marc Cheong explains.

Because of how complex and pervasive algorithms are, you can’t guarantee control over them. Nonetheless, you shouldn’t let tech giants’ bottom line dictate how you engage with social media.

We have no control of what we see on social media. This needs to end.
