The perfect recommendation system is one that fucks off until I explicitly ask for a recommendation and doesn't fund a shady network of data brokers hovering up every bit of data they can get their hands on. So it's not very like advanced ads technology.
Perfect according to whom? You are not developing it, your needs are only as relevant as it brings money to whoever is developing the recommendation system.
A recommendation system that never interrupts you is less rentable, it’s like discrete and decent ads, it’s called a phone book and it died a long time ago because there’s no money in that anymore.
