You brought in the term interface specifically to talk about the necessity to intentionally bridge two separate layers of reality. To use a computer, I need a KVM or touchscreen or whatever, an interface that samples the behavior of physical matter and maps it to microelectronic settings. I pointed out that in a truly digitial universe, no such thing would be necessary and nothing would be prevented by the lack of such a thing. Once something is native digital, it can be integrated with anything else that is digital native - that is sort of the point. It's all virtual. Any formalized virtual interfaces, a KVM in Second Life or The Matrix or whatever, are purely decorative. They are cartoon facades. The actual code doesn't need any kind of graphic representation or digital-to-something-to-digital transduction to pass from one area of memory to another. > > > There is no > > interface.

The virtual machine has the same access to the physical hardware as the root level. It's entirely up to the programmer how direct they want it to appear to the user, but ultimately, it is still just a program running on the hardware.
