I like your style of writing and I see where you're coming from. However I have to respectfully disagree. To minimize the human experience to nothing more than a transaction, a function, is, I think, a tremendous disservice and gross under estimation of our experience.
Computers are electrical. Binary. 1's and 0's. Simplistic and predictable.
However we are at least elecyrochemical beings. That secondary layer of chemicals, allows for a "quantum" spectrum of possibilities, in the quantum Computer sense. It is not binary, but infinite, and ever fluctuating.
Now I do very much agree that we have at least two layers, that is one which is authentic to who we are off line, and one online. But we have much more than that. We are different people around our parents, our friends, our distant family, our selves, our elders, our teachers, our students etc.. In fact the idea that we have one authentic identity that should never change no matter who we are with, I believe to be a fallacy. If I'm talking to my 5 year old son, I behave very differently than when I'm talking to my wife, or my sister. And I think that's OK.
I think my off line and online personas are probably closer together than most of my other "identities".
What do you think?
