why do you think people see faces in everything ? https://static.boredpanda.com/blog/wp-content/uuuploads/things-with-faces/things-with-faces-27.jpg https://www.iwastesomuchtime.com/wp-content/uploads-webpc/uploads/sites/68/2023/02/Faces-Memes-1-94490.png.webp because your brain automatically discards 99% of all information and only the 1% it deems relevant reaches your consciousness. faces are deemed relevant. other things not. you don't actually see 99% of what's in front of your eyes and a lot of what you do see ( like these faces ) isn't actually there. you may not call this an algorithm but it is certainly a filter and not very different from what Twitter uses to assemble your timeline.
