Just sharing a interesting paper.
Here we integrate the diverse modes of gene interactions (regulatory, genetic, phosphorylation, signaling, metabolic and physical protein-protein interactions) to create a unified biological network. We then exploit the unique properties of loss-of-function tolerant and essential genes in this unified network to build a computational model that can predict global perturbation caused by deleterious mutations in all genes.

Agree. I think more "global" approaches may not answer our questions but maybe brings us more information and directions for better understanding of this complex scenario.
