Yep. This. Algorithms by all companies seem to be less and less relevant to what I want to see. Even when I specifically say I want to see "X" in my stream, search results, etc. I keep getting shown "Y" only to find "X" buried somewhere.
The other problem - more so in Social Media feeds than in Search/email results is that algorithms seem to think if I like/plus/heart a post about something, say cows, that it means I want to be buried under an avalanche of cows. Now I DO like cows, but I also like fish, pigs, trees, tomatoes, grains, stars, and a gazillion other things. Algorithms seem hell bent on compartmentalizing us.
The other danger is I see more and more of my friends stuck in their own little echo chambers. This only leads to more and more misunderstandings (deliberate and unintentional). And quite frankly flat out ignorance as to other people's motives and real desires. To amend what Yoda so wisely stated -
"Ignorance leads to fear. Fear is the path to the dark side. Fear leads to anger. Anger leads to hate. Hate leads to suffering."
