I wasn't being hard on the OP. My observation is about the state of
*all* software.  My software especially, your software, Microsoft's
software.  It all is of rather poor quality compared to the rigors of
other industries like civil engineering, manufacturing, etc.

That's unfortunately, but seems to reinforce the notion that adequate
testing is required.  Clearly for a microchip, theoretically testing the
chip's "software" (for lack of a better term) was not adequate.  An
analogy to our software situation is that someone tested the algorithm,
but not the actual, in-use implementation of the algorithm.
