I think it's partly because since the Industrial Revolution education has mostly been communal rather than individual and in-family and small schools. The larger our public schools get, the dumber the graduates are and the more they think alike. Communial education tends to program minds into assembly line thinking in fields like science, building, manufacture design and so forth.
And you're advancing this supposed trend of getting "dumber" as a reason why people re-use design?
Then apparently the "dumber" they get, the more they resemble your all-wise creator.
Surely some mistake here?
