The author plot the input/output on a graph, intuited (largely incorrectly, because that's not how sufficiently large state spaces look) that the output was vaguely pretty, and then... I mean that's it, they just said they have a plot of the space it operates on therefore it's silly to ascribe interesting features to the way it works.
And look, it's fine, they prefer words of a certain valence, particularly ones with the right negative connotations, I prefer other words with other valences. None of this means the concerns don't matter. Natural selection on human pathogens isn't anything particularly like human intelligence and it's still very effective at selecting outcomes that we don't want against our attempts to change that, as an incidental outcome of its optimization pressures. I think it's very important we don't build highly capable systems that select for outcomes we don't want and will do so against our attempts to change it.
