this is a jumping off point into considering your own mind as an illusion. your own self with its sense of personhood: i.e. yourself as the it-element in a I-it interaction.
But if we leave it at that, it's essentially a very nihilistic (deterministically reduced), so either turn back, or keep going:
the fact that your own personhood is itself very much an illusion is OK. such illusion, however illusory, has real and potentially useful effects
when you interact with your computer, do you do it terms of the logical gates you know are there? of course not, we use higher level constructs (essentially "illusory" conceptual constructions) like processes and things provided by the operating system; we use languages, functions, classes: farther and farther away from the 'real' hardware-made logic gates with more and more mathematical-grade illusions in between.
so the illusions have real effects, in MOST contexts, it's better to deal with the illusions than with the underlying implementations. dunno, what if we tried to think of a HTTP search request into some API in terms of the voltage levels in the ethernet wires so that we truly 'spoil the illusion'??
