I think it's entirely possible and really not even that hard to "fix" Facebook. Zuckerberg seems more intent on pivoting to nonsense like Portal and Metaverse with no actual foundations. It's Zuck getting bored and letting his ego ruin a cash cow that can easily be a force for good in the world if they just tried. I think the only way this ends is with Zuck losing his job as CEO. He tripped up the stairs for 15 years and now thinks he is a visionary.
