I've no clue why people have downvoted this; you're right as rain. A phone is nothing short of a digital slot machine and shouldn't be put in front of adults or children. These algorithms are designed for profit, not humanity. They have far greater control over us than they should.
The funny thing is, they don't even have control. They can't push propaganda. They can just accelerate human desire. Through all the brain rot they have created, they didn't even gain anything significant, just a few % bump in "kEy pErFormAnce iNdiCatoRs".
Capitalism is a system that rewards the selfish and greedy. If you don't pursue every bump in key performance indicators you can, then someone else will and they'll eat your lunch.
