Relationships and sequences.

But if you want to talk about REAL complex systems talk to a microprocessor logic owner or architect trying to shoot a bug.

A while ago we found a bug that could crash a system (fixed in a new RIT of the chip) if we did X then Y in state … we didn’t know.

Listening to the various leads for the sub-units on a phone call trying to reason about what was happening I found myself visualizing this increasingly complicated steam powered machine, with parts sprawling, tiny gears whirring, and bits zipping about whenever X happened.

It was humbling.
