Interesting Talk: "The Architecture of Uncertainty"

I've just watched this great talk by Kevlin Henney:

• The Architecture of Uncertainty

This talk gives great insights in the relationships among uncertainty, design, learning and change.

Lately I've been reading and thinking a lot about this after reading Sandi Metz great book on OO design and several interesting discussions with @remosu.

Some intuitions are growing in my head but they are still quite fuzzy.
