All this reduces to is the old notion that life is just a normal aspect 
of the existence of matter in our universe.  Matter just naturally forms 
what these physicists are calling machines.  Elements like gold can only 
form in exploding supernova or stellar collisions, but for some reason 
the scattered debris can form nuggets of pure gold and other elements as 
well as crystals of other materials forming out of the mess.  Molecules 
of mutliple elements can form spontaneously.  These aggregates of matter 
can have catalytic activity and can make more molecules.

Simplistic "machines" are constantly being produced when the elements 
are in high enough concentration to allow their production.  What we 
consider to be life (simple bacteria) are a complex combination of many 
simple machines that are kept aggregated in order to produce more of the 
same simple machines.  Eukaryotes are combinations of lifeforms 
(chloroplasts, mitochodria and the nucleus).  Metazoans are 
conglomerations of cells.  They are continuing the meme by claiming that 
lifeforms can form aggregates with matter to form a giant biosphere machine.
