Why would a personal AI which curates your content be any “better” than FB’s AI which curates your content? Isn’t the current AI based on what you end up engaging with anyway? If you naturally engage in a variety of content across all ideological spectrums, than that’s what the FB AI is going to predict for you. Unfortunately, the vast majority of us engage with content which reinforces our existing worldview - which is exactly what would happen with a personal AI.
Because an algorithm under your control can be tweaked by you. Could be as simple as reordering topics on a list of preferences. Facebook's algorithm can't be controlled like that. Also, an algorithm you own won't change itself unbeknownst to you.
