A program is made out of mathematical components, which have a definition, whereas physical objects don't have a definition. The matter does what it does, so through the perversity of matter, your design may not work the way it &ldquo;should&rdquo; have worked. And that's just tough. You can't say that the matter has a bug in it, and the physical universe should get fixed. [Whereas] we [programmers] can make a castle that rests on a mathematically thin line, and it stays up because nothing weighs anything.
