Lord English’s symbol being a black hole, or singularity, is a double entendre - because a “singularity” is also the hypothesised end result of machine supremacy, the point at which technological advancement outstrips human advancement and spirals out of control. AR alludes to this theory when he brags of “the jaw-dropping speed of [his] post-singularity cognition.”

the machine uprising, à la the Terminator, is the inevitable outcome of technological expansion in just the same way Lord English himself is the embodiment of inevitability itself!
