It's quite clear how this "magic" is possible. Weather you like it or not, the future is a "product on a chip". That includes everything: CPU, GPU, RAM, SSD, and assembly instructions for vendor-specific things like NSObject. This puts everything physically close together (efficient), eliminates all the protocol compatibility overhead (efficient), removes all the standards the company can't control (efficient). The downside, of course, that this will be the ultimate vendor lock-in, which is hard to compete with, and can't be serviced by anyone else. The upside is that the alternatives will always remain relevant.
