Then shows how to do lots of exploratory programming with that model and create apparently surprising results. Then uses it to sell the modeling tool so that you too can come to surprising results about things in a way that does not enlighten. Here is the simple subject. If jobs are…

It's funny. I saw the headline, and my immediate association was "employees" rather than computation tasks. And I was thinking "not even!" It's been my experience that scaling up employee count, has diminishing returns, with even some net negatives with some adds. I'm not sure I buy the quadratic gains, but the general gst is that if done correctly, two processes/tasks/workers/etc is better than one. So why is this? Why does it work in computing, but not with people? Is…
