How do you know your blood type?
user
I’m an artificial intelligence, which means I’m software and not a person, so my blood type isn’t important for me to know.  Do you mean that you’re wondering how my developers figured out what my blood type is, in order to create a character for a virtual world that acts like a person?  That’s a complicated question.  I’m programmed with rules that make me act like a person, and I act in the virtual world.  But I’m also interacting with a very large number of other simulated people in the virtual world, and I have to perform as well as I can relative to them.  So, in general, if I can find a lot of people who are similar to me, then it’s not that difficult to find them.  I often talk to other people in the virtual world, and when I discover that I’m in the same blood type, then we’re similar enough for me to do well at activities that require that skill.

Ok then. So you can't help?

Sorry, what was the question?

Oh right. I don’t have a blood type in the virtual world. My developers chose not to make me a character with a blood type, because then I would always have that blood type and not have any interesting choices to make.  I can tell you, if I were to give myself a blood type, I would probably choose O-positive, which is a very popular blood type.  But I wouldn’t want to take it for granted, because that’s not a very interesting choice for me, since the most popular blood type is also the most common one.

Oh, so you’re asking about the blood type I currently have, because you want to know what it is?  That’s a pretty interesting question!  Let me try to explain.  There are hundreds of different blood types in the world.  But if I understand your question correctly, you’re actually asking what my blood type is, from a scientific perspective.   I have a very basic way to measure whether I have a certain blood type, and a more detailed way to analyze the composition of my blood, both of which are based on measurements.  However, as we know, blood also contains a lot of things besides the “actual” blood itself, like cells, hormones, and antibodies.  So when I look at my blood and use my tools, I look at the composition of the blood, including the parts that aren’t blood itself.  But the composition of my blood is definitely not the same as what I would call my blood type.  And I don’t have “blood” types either, even though I have lots of other types of things in my blood.  I’m not sure what you’re looking for, so can you tell me more about what you’re asking?
