In the course of a thoughtful post on Crooked Timber about why you shouldn't upgrade software, there are two extras of excellence. First, a snide comment about Microsoft.

It would be nice to think that Microsoft is somehow to blame, but this is very unlikely. Although Microsoft’s products are up to trivial tasks like writing letters or making dogs fly or running the electronic voting systems of the United States, no-one would trust them with something like a transactional database, an air-traffic control system or an electricity grid.

This also simplifies modifying the program, should the value of PI change.
