Probabilistic engineering and the 24-7 employee

> We are rapidly moving from deterministic engineering to probabilistic engineering, and our tools, our training, and our organizational instincts are still built for the old paradigm.

There's some bad news: it's never been a non-probablistic engineering.

A key word is Failt-tolerance.

The engineering has never been fully deterministic. Same as running the systems.

So nothing's changed in this area.
