It seems to me that NosyNed's example below satisfies Behe's description of irreducible complexity:
NosyNed writes:
[T]his is a stone arch. This fits the definition of IC. Remove a stone and bang! down it falls. You can NOT build an arch one stone at a time if that is all you have.
If you pull any single piece of the arch out, it collapses. The arch cannot stand without every existing component remaining in place.
So we have a designer, and a designed structure that cannot function without every bit of the design remaining in place.
Doesn't this satisfy your question about why we haven't invented irreducible complexity? We most certainly have. What this invention of irreducible complexity demonstrates is that a current state of irreducible complexity does not require that the structure be magicked into existence complete.
