Ultratech is the highest grade of technology that can be maintained and operated by subsingularitan sentients, only requiring tranasapient assistance to set up the initial training and support structure. Unlike Hitech, ultratech is derived, in part or in whole, from technology originally devised by transapient entities. Very often the original idea for an ultratech concept has been conceived by a modosophont scientist or imagineer, but the actual technology has been brought into reality by transapient minds.
Ultratech can, in theory, be reproduced and maintained by a modosophont society indefinitely without further transapient assistance. For that reason it is popular with many clades and polities that wish to remain autonomous from transapient hegemony. It is also very popular in modosophont Free Zones, and widely found in many NoCoZo polities and member worlds. A very decent interplanetary-scale civilization can be maintained just through ultratech alone.
Particular examples of ultratech are monopole and magmatter engineering, conversion technology, deep well industrial zones (transmutation forges). Ultratech artifacts and products not uncommonly can be found in Hi, Middle, and Low tech civilizations, polities, and worlds, who usual acquire it by trade, foreign aid. or inheritance. It can also be found in Transapientech Civilizations, usually as fads or curiosities.
Augmented Superbright sophonts are typically required to operate ultratech though in some cases devices are best operated by dedicated hyperturings, although this can frequently be mastered by augmented sapients with some or great effort. Much depends on the type of tech. Although most ultratech is configured to be baseline friendly and "idiot proof", this is not always the case.
Ultratech is ubiquitous throughout the Sephirotic polities and other developed worlds; most commonly in the NoCoZo and Terran Federation, but also very often standard elsewhere. It is even found commonly in many polities isolated from the Wormhole Nexus, as well as in the hinteregions and Outer Volumes; in fact anywhere that sophonts can set up an advanced manufacturing base and have good access to data and raw resources.
Ultratech civilizations and societies differ from hitech societies largely in the degree of their interdependence with transapients and of course in the even higher degree of power and wealth they provide to members.
Angelnet - Text by M. Alan Kazlev, with additions by John B and Stephen Inniss Any dense network of technology and artificial intelligences that establishes a very high degree of control over a region, generally with beneficial intent towards the inhabitants. The archetypical angelnet is under transapient control and makes heavy use of utility fog, and may cover an entire large hap or a planetary surface, atmosphere, and orbital space environment. Less pervasive or less sophisticated angelnets are also widely used.
Dumbo - Text by M. Alan Kazlev Dumbdowned tech; ultratech that has been modified so that even a baseline can use it. There are two types of dumbdo - augie and duh. Augie requires augmentations such as DNI, waldos,and so on. Duh, also known as ugie, can be used even by an unaugmented baseline. Even augie dumdo is limited relative to what can be done with the tech by a hyperturing or power. Duh is even more restricted.
Dyson Node - Text by M. Alan Kazlev A dyson sphere made mostly of computronium and dedicated to processing needs, as submind of a larger archailect. Such megastructures (such as linked Jupiter brains) are part of a larger archailect; connected via interstellar wormhole buses to other nodes. Generally there will be shells concerned with non-processing functions (manufacturing, maintenance, defence, wormhole bus control system) as well.
Dyson Ring Swarm - Text by M. Alan Kazlev A partial dyson swarm in which the component orbitals and other megastructures follow conventional orbits and form a ring, or Rings around the star around the star.
Exotic Energy - Text by Steve Bowers The common term for averaged null energy condition (ANEC)-violating negative energy, also sometimes known as phantom energy.
Exotic Matter - Text by Stephen Inniss In popular usage any highly unusual "unnatural" matter that is not composed of protons, neutrons, and electrons. This includes such substances as quarkonium, magmatter, harmonium, pentaquarks and Q-balls.
Hypertech Economics - Text by John B There are, in various sectors, subsets of the archailects whose sole purpose is tracking and correlating economic data. Economics thus becomes a synergistic add-on to memetics - "Gee, those doodads are expensive - must be good!" or "Gee, those doodads are expensive - gotta be overpriced!", depending on the memetic spin.
Mechology, Mechosystem - Text by Todd Drashner Colloquial term for the entire system of non-sophont machines, databases, programs, etc. that supports and controls the infrastructure throughout most of the civilized galaxy.
Monopoles - Text by Adam Getchell Elementary particles that carry units of magnetic charge. Artificial monopoles have a great many uses.
Star Lifting - Text by Dave Criswell, in Anders Sandberg's Transhuman Terminology Removing material from a star for industrial use or for stellar husbandry. Methods include increasing its rotation until material begins to drift off the equator or squeezing it using intense magnetic fields from particle accelerators.
Starbooster - Text by Todd Drashner A solar output enhancement array. It consists of solar sails placed in balanced positions above the northern and southern hemispheres of a star. The array reflects the output of the star back onto its surface, thereby heating the outer layers and causing the star's spectrum to shift upward. The result for planets and habitats orbiting in the plane of the ecliptic is that the star appears to change from its original classification (typically M or K) to a more Sol-like spectrum (G-class).
Stellar Husbandry - Text by Dave Criswell, in Anders Sandberg's Transhuman Terminology A type of stellar engineering which involves controlling the evolution and properties of stars, especially to stabilize them, prolong their lifetimes, manipulate the stellar wind, lift off useful material or create new stars. Typical methods include star lifting or mixing the stellar core with envelope material to make hydrogen burning last longer.
