[The Culture] Are the Idirans right?

The Idirans consider The Culture as an evolutionary dead-end, is this in any way true? Is there truly anything beyond The Minds?

Not in this universe. The Sublimed move on to greater things, in the rest of the universal dimensions - far beyond those that even a top of the line GSV can manipulate. In a way, the Minds (and those beings uplifted to them) are the next step in evolution because they can Sublime ALONE, rather than needing to do so as a race. And beyond that, you get things that create events like the Excession and use it as a bridge to step between universal toroids to escape heat death.

The Culture was a bit too close to the original near-exterminators of the Idirans for their liking. The Idirans were nearly annihilated by hostile invaders, transforming themselves slowly into a religious warrior race after throwing the invaders back (And exterminating them, too). Sure, they were mostly benign, but it was still annihilation of a species and the end of a culture once it was introduced to the Culture. It was dressed up as religious reasons, "Fuck those guys for being too much like these guys" was closer to the truth.
