Diversity of thought - of which google is now less of.

You switched your argument from one comment to another; it's unclear what your position is.
my position is very simple: sheep don't need to hear a wolf out. there is nothing to discuss.
Diversity of genetics is not the same as diversity of thought. The word is being equivocated from one context into the other.
It is an old argument that one's ethnicity determines one's personality. I can't say one that I support.
