> Honestly, if you're thinking about all the levels an application is built upon, it's a miracle things even work. One mitigating factor is that all those russian-doll levels don't switch back and forth all that much (thinking in computer, not human, time). Moreover, some of those levels (like the BIOS) do their thing and then they cede control until the end of time (i.e. reset). So yes, the multilayered cake is pretty impressive, but the situation is not that dire.
