The youtube algortithm:<br><br><br>1) Show the user what he has clicked on<br>Help a friend with a subject that does not interest you, and research it with youtube and google; the result is that youtube will now recommend said subject for the rest of your life, regardless of how man times you tell youtube "not interested", "dont show content from channel".  Test this, try clicking "home", then click not interested to the subject that does not interest you, then click refresh and confirm that you might as well have written your preferences on toilet paper and flushed it down the drain. To give an example, I helped a family member research which guitar to buy, and I have clicked "not interested" to 100+ guitar videos, but I always get at least 10 guitar video suggestions, every time I click Home. Also, when I click home, youtube will recommend 20 videos that I have already watched. <br><br>2) Show the user only what is politically correct <br>Show the user only pop culture, commercial content and politically acceptable content<br>Youtube and google censors content. I know this because I have used search engines from before google existed, so I know what content I am supposed to find, and it does not show up, in the search results. During the last couple of years, this has gotten so bad, especially with regards to fringe subjects and subjects that might be considered "dangerous". UFO's, pyrotechnics, assassination techniques, etc. If you are an expert on such a subject, you can verify that what I say is true ... newcomers will have no clue this is going on and will just be presented with misinformation OR no information.<br><br>3) Show the user what other's have clicked on<br>Sigh. Corona virus (not interested), sports (not interested), pop music (not interested), etc, etc, etc.<br><br>4) What is going on ?<br>As far as I can see, the algorithm is optimized to protect the powers that be, keep us stupid, enforce political correctness and maximize our consumption. No amount of feedback can train the algorithm to show high quality content in your fields of interest UNLESS your interests are in line with what I have written above. If your feedback, which is limited to "not interested", is not used to help show you recommended videos in your fields of interest, what is it intended for ? More profiling ? How does the algorithm adjust, when you click "not interested" ? Am I not interested because the video is less than 20 minutes ? Am I not interested because the content is not technical enough ? Am I not interested because I don't want to listen to some of the persons in the video ?<br><br><br>If this is AI ? Or could you write 100 lines of classical code (logic, functional or procedural) that works better than the AI they have spend millions developing ?
