there is no such thing as software

just variations in hardware, such as the magnetic polarization of bits on a hard drive

Also, I presume you are the guy from the one thread where we talked about universal dovetailers (and you said it was an example of an observer). Correct me if I am wrong.
You said something about not being able to find all observers in a system when I said something about "scanning for observers" partially in jest.
But, you didn't say it's impossible to "scan for observers", just impossible to find them all? How would one find these observers then, in case computational structures really can have consciousness?
