An algorithm developed by computer, which is based on your personal, social, political and other opinions. Commonly used by social media and eshops. This is what cookies are for. The algorithm then basically shows you more content like the one you clicked on earlier.
Positives: Ads that pop up are more relevant for you and servers like YouTube is going to show relevant videos for you.
Negatives: Often leads to extremism these days, especially during the covid-19 pandemic because people often get to certain social bubbles on social media, where are only other people with same opinions. This makes them closeminded and and think that they are woke.
Be very careful with your social bubble and try to pop it if possible. Listen to people with different opinions otherwise you end up as dogmatic as the catholic church during the middle ages.
Jamall: Yo we should talk more to Roy, cause he's trapped in his social bubble and is starting to talk shit about Oompa Loompas who built the pyramids and wanna kill anyone who says Chipotle 3 times in front of the mirror at midnight.
Phill: Yeah he's a good guy, we should not let that happen to him.
