Richard Cook (on resilience of complex systems)

gistfile1.txt

I think you have to open the objects and open your methods. I think that
this idea of hiding in layers of abstraction everything about the
details has, in fact, pretty much run its course now. I think the idea
that we can make these sorts of black box devices that we only know
about the shell of and have no knowledge of the internal workings of is
in fact a deep mistake. Because it turns out that in order to be able to
reason about how the system is actually working, we have to have
knowledge about what is inside the black box.
