Indeed, but the real opportunity now with so much whole-genome data 
circulating around is to create such a large model just as a starting point 
and then to simplify it to the point of making it understandable (still 
keeping its predictive ability).  This is where modeling becomes 
interesting!

The main advantage of whole-genome data is that the observation is not 
biased (i.e. we are looking at all components of the system); another 
positive aspect is that the data are consistent (i.e. all the components 
measured in the same conditions).  The latter point is the main difficulty 
in creating bottom-up models where the kinetics of each enzyme are measured 
in different conditions often making the models inconsistent.
