Gleister duplication cascade
The Robot Who Looked Like MeThe Gleister duplication cascade is the multiplying chain of replacements that follows each Gleister’s use of a time machine. In the explanation given by Mingus, every departure leaves a vacancy in space-time, and Nature fills it with another Gleister; when that replacement also travels, it leaves another vacancy. What begins as one journey therefore becomes an exponential population crisis. The cascade makes time travel not merely a way to move through history, but a process that continually alters who occupies it and ultimately overwhelms the Empire that tries to manage its consequences.
The Replacement Mechanism
The account begins with the first, or original, Gleister building a time machine and going into the future. His absence from his normal position leaves what Mingus describes as a hole in the space-time fabric. Nature supplies an identical or nearly identical Gleister to fill it, as though drawing on spare parts. The new arrival is not simply a record of the traveler: he occupies a place the traveler has vacated, making one journey the cause of another Gleister’s presence in the world.
The replacement rule applies again whenever a Gleister uses a time machine. Each departure creates another opening for Nature to fill, so the duplication is not a one-time consequence of the first invention. A Gleister who travels can help produce the circumstances in which another Gleister appears; that new Gleister can travel in turn. The process is recursive, with each new time-traveling sequence contributing to the next generation of arrivals.
Multiple Paths and the Problem of Identity
The cascade produces several Gleister sequences rather than one stable line of personal history. Mingus identifies a sequence that becomes Emperor and another that forms an organization against him, alongside other sequences pursuing their own missions. The population therefore grows through histories that intersect and diverge: Gleisters may share an identical past up to the moment they encounter one another, but contact becomes a new input that makes their subsequent paths different.
Charlie Gleister’s understanding of his own future reflects the unsettling logic of this arrangement. He anticipates getting his machine working, traveling forward, then returning to meet himself shortly before inventing it. Another Gleister confirms the outline, while Charlie recognizes that the situation is strange. The encounter is not presented as a simple return to an unchanged past: the rule that reality is positional, together with the idea that nothing happens for the first time, makes the meeting part of a history already shaped by recurrence and displacement.
A Gleister who realizes that he has helped multiply his kind cannot simply undo the process by returning to before the invention and refusing to build the machine. The other Gleister’s experience indicates that this is not an available escape. The past is not an empty niche waiting for a returning traveler to occupy it: everything modifies everything, and there is no unchanged version of the self who could step back into the earlier position. Nor would persuading another Gleister to abstain provide a clean reset, because there is not just one other Gleister to persuade. There are multiple potential counterparts, identical until contact and different thereafter.
Exponential Growth and Imperial Crisis
The branching sequences make the cascade geometric rather than gradual. Mingus warns Hieronymous Gleister that hundreds become thousands, then millions, trillions, and quadrillions. The escalation is central to the crisis: because each time-traveling Gleister can be implicated in the creation of further Gleisters, the growth accelerates before any authority can respond effectively.
The arrivals have nowhere else to go and come to the Empire. Mingus reports that he has housed about twelve million Gleisters, but that the Empire is running out of resources while new ones arrive at an increasing rate. The number already accommodated is thus not evidence that the problem is under control; it marks the scale of a burden that is still growing. Each attempt to contain the consequences confronts a larger version of the same problem.
Mingus says that even shooting the Gleisters on sight would not control the mounting progression. In his projection, the Earth would eventually be carpeted with them, while new arrivals continued to pour in. The image converts an abstract mathematical sequence into a physical limit: there would be no space left for anyone else, yet the cause of the crowding would persist. The cascade is not merely a population problem that force can solve, because every new displacement replenishes the process that produces it.
The Emperor as a Consequence of the Cascade
The Empire’s ruler is himself one branch of the multiplied history, not an authority outside it. Mingus explains that the Emperor sequence and the resistance sequence both emerge among the Gleisters generated by time travel. In a confrontation with Egon Gleister, Mingus is told that returning to the past has already meant he is no longer the Emperor; there is no single, definitive Emperor separate from the sequence of events that made one Gleister ruler. The explanation connects political identity to temporal position: the title belongs to a particular path, not to an unchanging person who can carry it intact across every displacement.
Mingus’s image of the Emperor as the slave of time gives the cascade its governing irony. The ruler can house millions and consider force, but cannot command the process at the rate it reproduces itself. The very time-travel histories that yield an Emperor and an opposition also generate more Gleisters than the Empire can accommodate. A political contest that might appear to concern who rules is overtaken by a prior question: whether the world can contain the multiplying participants at all.
