To answer these questions, I wrote a Python program that generated a long list of random numbers (1,000 elements) according to the Gaussian distribution with mean 0 and standard deviation 1. I expected it to stay close to 1, and the experiment would serve no purpose other than exercising my laptop’s fan. 0004 at 10,000 iterations.

The unstated assumption behind this discussion is that, if we don’t reduce the workforce as routine tasks get taken over by machines, we need to re-skill them so that they can move into other parts of the institution and perform a different set of tightly specified and highly standardized tasks.

This exercises the model’s code and surfaces issues and exceptions, which can be readily examined and resolved in a controlled environment.
