Glad that Stephen brings up the diversity perpective. Discussions about diversity and how to let it do its normal thing are probably more useful than discussions about curriculum and other physical concepts.

Diversity seems to be fundamental to any ecosystem. Diversity like learning happens no matter what. What is important with diversity is to recognize its value early and not to mess around too much with the processes that causes it. Let nature do its thing.

In the learning world diversity does not necessarily require that we learn different things. For example if we take a different path to get to the same results we will have diversity.
