матрёшка мозг…

The idea of a matryoshka brain combines Freeman Dyson’s most famous concept with an almost unimaginably large and powerful computer. A Dyson sphere would be a megastructure completely enclosing the Sun capturing all of the solar energy while simultaneously providing an interior surface area many times that of the Earth. Presuming a radius of one astronomical unit (AU), the distance between the Sun and Earth, the area of the inside of the shell would be about 550 million times the planet surface.

Robert Bradbury (presumably no relation to the famous sci fi author) proposed that in addition to absorbing all the power the Sun emits the enclosure would also be one massive computer. Assume a circuit panel about the size of a sheet of printer paper. It would take roughly 4.5 quintillion such panels to cover the inside of a 1 AU Dyson sphere. Using only today’s computing power the capacity would be mind-boggling.

A hard sci fi author by the name of Charles Stross added another feature. He has imagined that minds could be uploaded to such a computer. It has since been the subject of some speculation that an intelligent species somewhere in the multiverse has made all three of these technological advances.

All this to say that the virtual environment provided by a matryoshka brain is one of a very few in which minds similar to our own might not have some form of hierarchy. There are many variations of the notion that “time is what keeps everything from happening at once.” An organizational chart is what keeps everyone from giving orders to everyone else. There’d be too much confusion. Mutually assured insubordination.

This doesn’t necessarily mean that a matryoshka brain would be indistinguishable from a hive mind. It also isn’t a foolproof method for skipping the leader-and-subordinates system. However, a computer with this much power would in all probability be omniscient about the activity of each component mind it hosted.

A matryoshka brain unimaginably far in the future. Astral is set only about 550 years from now. Today’s sociopolitical climate has become a bit obsessed with unfettered individual liberty. A month or so ago I overheard a mother trying to determine why her child was getting terrible grades in school. The frustrated student eventually said, “But you told me to never let anyone tell me what to do.” In and of itself that’s a bit of a paradox but that’s another story.

While considering this and working on world-building for the novel, which is part police procedural thriller, I wondered if authority would still be divided over different tiers of officers. In a pseudo-hive mind there’d probably be no crime; if you know what everyone is thinking anything illegal could ostensibly be prevented à la Philip K. Dick’s Minority Report. He alreadyrank covered the idea of using precognition in circumventing crime and I’m going down a very different road.

So — one of the main characters of Astral is, in fact, a police officer. She does report to someone and supervises a team of seven others. She does wear a uniform and it does contain some circuitry. The exact capacity of this tiniest final doll in the metaphoric nested computer chain isn’t going to be treated here but I have been looking for a reason to have rank displayed on a special screen woven into a uniform for about three years now.

The likelihood that police detectives will abandon rank in favor of consensus or telepathic gestalt any time soon seems as remote as a breakthrough leading to the imminent construction of a computer 200 million miles across. If you discover evidence to the contrary, please let me know. The uniform rank display will turn up somewhere else.
