A very reasonable predictor for 'what is Apple going to do next' is to look at what Microsoft was doing 5 years ago. Flat design, Surface, desktop/tablet mode, Universal Apps, mobile-first design across the desktop, splitscreen windowing, Hololens, Copilot, GenAI throughout the OS, 'Game Mode' and a game bar overlay, phone mirroring, foldable phones. It's exhausting to watch Microsoft do cool things, have them fall on their face, and be discontinued before becoming standard across the industry
