Why development is needed for future?

Within the evolutionary computation community, there is a strong consensus to agreed on the need of indirect representations to achieve scalability. But no such consensus has been yet found on how to design an indirect representation. An idea to build a scalable representation, is to see the phenotype to genotype mapping as an iterative transformation process: an explicit development stage. But such an approach is computationally expensive and then it relevance might be questionable. Through a simple, accessible example, optimization of a block stack overhang, it is shown that, indeed, an explicit development stage can be the only way if one wants a scalable representation and/or scalable solutions to a problem.
