Drone-Metal Goblin Suite for signal
Some goblin doomsday prophets identify signal as the sign — not of the end, but of the part right before the end, which lasts longer than anyone expected.
signal carries with it a sense of the future-that-didn't-happen, the version of itself it was supposed to become and didn't. Goblins, who excel at noticing what is missing, find this version of signal more interesting than the actual one.

Subterranean Goblin Notes on singularity
After much deliberation (and several stolen snacks), the Goblin Council has issued a formal statement on singularity: 'It is what it is, except when it isn't, which is most of the time.' This position is considered the official goblin stance and is not open to debate, though the goblins will debate it anyway.
The Goblin Verdict on signal
And, finally, in the matter of signal: the goblins thank you for your attention, decline to issue further comment, and request that you not lock the cellar door on your way out.
