This question lies at the heart of 21st century medicine.  Is there really anything to human existence but a cluster of measurable vectors?  We must ask this question, because the implied answer is NO.  Medicine is alleged to be an exercise in logical positivism.  Modern technological medicine finds it simply mushy metaphysical fairydancing.  You are not “human”; you just think you are, say the logical positivists and mental technicians of healthcare.

Do humans cry?  Or is it a parasympathetic response?

I believe that our being does not arise from a finite classifiable set of rules.  Yes there are genes; they are finite in number.  Yes, there are cells; they are finite in number.  But we do not have an algorithmic sequence that can be initiated to synthesize a human entity.  We DO reason; we are not the product of it.

Computers, on the other hand, ARE analytic entities.  They arise from a coherent, quantifiable set of rules.  They can mimic human behavior, mostly because of how we perceive their actions, rather than having any “existence” as we think of it.

In the direction of digital epistemology which posits that given enough data, one can map a universe which mimics reality to any predetermined degree of accuracy; therefore, we can model reality.  We fool ourselves into believing this.  It is provably false.

Artificial Intelligence is thriving not because machines are getting smarter, that is not the only reason.  We humans are getting dumber; we are confused into doubting our own humanity, and the difference between humans and computers. Computers, unlike humans, do not worship their logical excreta.

Medicine is posited to be a set of analytical rules spanning a finite space.  It is not an example of our piercing insight that we imagine this to be so; rather, it is a clear symptom of our ignorance and superstition.
