         | I just read the abstract and some of the discussion. He is
         | saying something interesting, however the language is pretty
         | opaque if you aren't doing philosophy of science.
         | 
         | As I understand the abstract (ruthlessly oversimplified):
         | 
         | 1. Emergent behvior is interesting.
         | 
         | 2. We don't really understand how to theoretically model
         | emergent systems. Emergent properties are high level, the stuff
         | we can measure is low level. Connecting them in a principled
         | fashioned is hard.
         | 
         | 3. We don't know if the limits are in the catgorization or
         | aquisition of knowledge.
         | 
         | 4. We are proposing a pragmatic bottom up approach which, like
         | granger causality, bypasses some of the hard parts.
         | 
         | 5. We test the approach on an artificially hard problem and got
         | good results.
         | 
         | 6. We think this has use elsewhere
         | 
         | It helps if you understand he's working in theoretical biology
         | where they see emergent systems at all levels and the inability
         | to model these systems jn a principled fashion is a real drag.

         | The paper is annoyingly opaque, and it would take me a few
         | hours, at least, to validate whether it's interesting at all.
         | This is typical of crackpot papers, so I'll simply reject it.
         | 
         | Also, if it were genius, it would probably have received more
         | than 6 citations after five years.

           | From the title, I was hoping for something on how to get more
           | complex behavior to emerge from machine learning systems. Or
           | at least a discussion of why self-improving systems seem to
           | max out after a while. It's not about that. Not even close.

       | Just from the abstract I learned two concepts. Granger causality
       | and Downward causation. Do scientists actually know these
       | concepts like the back of their hand and are able to read that
       | abstract in perfect clarity?

         | imagine they don't all know Granger causality. They actually
         | might be more likely to know Downard causation given some of

         | Downward causation is certainly part of the core terminology
         | when discussing the philosophy of emergence, like strong vs.
         | weak emergence. At least some scientists are also familiar with
         | it:

         | I had to look up both terms. Granger causality seems like an
         | intuitive concept and I am thinking the unique contribution of
         | Granger is making it computationally rigorous. Wikipedia, at
         | least, doesn't give a rigorous definition of downward causation
         | - nothing sufficient to distinguish it from lots of other
         | similar concepts.
         | 
         | And...that abstract is very, very difficult to read. My most
         | charitable explanation is that the author is carefully using
         | terms with very precise meanings in scientific philosophy, but
         | I have my doubts.
