1. I think that I want to calculate the sum of 1 and 1. I get a result (even several different results). I might think: "hey, brain, you do exactly what I want. How did you know what to do?" I might also think: "I am thinking", where my perception of "I" includes the little homunculus living in my brain.

2. I look at my right index finger and I decide to move it. It moves. I might think: "hey, finger, you do exactly what I want. How did you know what to do?" I might also think: "I am moving", where my perception of "I" includes my finger.

3. I look at the (computer) mouse, on the mousepad, on the table. I decide to move it. It moves. I might think: "hey, mouse, you do exactly what I want. How did you know what to do?" I might also think: "I am moving", where my perception of "I" includes my mouse. (And the mousepad? And the table? Is this also me?)

4. I look at the mouse cursor on the screen. I decide to move it. It moves. I might think: "hey, cursor, you do exactly what I want. How did you know what to do?" I might also think: "I am moving", where my perception of "I" includes the cursor on the screen.

5. I do a little bit more, write down these ideas - through fingers and keyboard, save it to disc, re-open the file, read it, edit it, save it again, publish it on the internet. I might think: "hey, computer, internet, you do exactly what I want. How did you know what to do?" I might also think: "I am doing something", where my perception of "I" includes the computer and the internet.

All that (alternative perspectives in 1. - 5.) is not really a problem in a fuzzy world of partial truth. It's a non-issue similar to the question of when do tones become a melody, when does an ovum/embryo/fetus/baby become human (so that we are allowed/no longer allowed/start to be able to kill it), how many people are needed to replace a light bulb......

However, it is a big problem in an XOR world, where there is only one truth. Or when the computer program screen designer must decide how the program interacts with the user. More precisely: Does the computer interface act on my behalf ("my files", "mypersonaldotcom", or does it call me "you"? Does it present itself as an extended part of me (like my brain, my finger, my mouse, my cursor, my computer; me the brain, me the finger, me the mouse, me the cursor, me the computer), or does it perform a dialogue with me as a separate entity/person? This concept being called "personalization", where is the boundary of the person? Here is what I observed:
