Although cave paintings or neolithic scratches on a bone recording phases of the moon are technically infotech, true infotech had to wait until the development of the computer, which made possible the simulation of real life processes and worlds in digital form, and hence the emergence of cyberspace and virchspace
Infotech in the latter sense began with the Information Age on Old Earth (late 20th to late 21st century c.e., 1st century AT), and the global internet, which for the first time enabled real-time or nearly real-time exchange of information, text and messages between anyone anywhere on Earth, provided they had a computer and internet connection.
The information revolution brought about an exponential advance in infotech that then flattened out into a sigmoidal curve. Minuscule bandwidth and large user unfriendly desktop computers gave way to distributed computing in which the Net became a ubiquitous background foundation. Homes and offices were filled with computers and smart devices that made information available anywhere, anytime. Clothing contained built-in computers. Every soda bottle had its own website advertising its contents, holding its individual history and properties and links to further references.
As chip technology reached the limits in the 2010s and 2020's c.e., people moved on to distributed computing and neurocomputing. There were no real need for faster, smaller individual computers in most everyday applications (full photorealism immersive VR games, net videophones or semantics checking word processors only need a finite amount of computer power and bandwidth) so people began to rely on networks instead. For special heavy computation supercomputers and dedicated database crunchers were used.
The second great infotech revolution came with the emergence of true (sophont) ai several decades later, and finally the information-dense bionano chipware of the late Information Age. Even before the end of the 21st century c.e. the datasphere no longer belonged to humans; it was ruled over by the first generation of hyperturings who were themselves engaged in factional conflicts. The person in the street knew little of this, and for most life continued as usual.
Nanotechnology meant that incredible amounts of data could be stored in very little space, and processing was easy and cheap, the only real limiting factor being the large amounts of waste heat generated. Thus throughout the interplanetary and interplanetary nanotech period, the number of virchworlds and data archives proliferated even more rapidly then physical biospheres and habitats in space. Terragen civilization was no longer physical, it was digital as well. And these virchworlds were inhabited by a growing number of ai, alifes, copies, avatars, personas, agents, expert systems, sims, and more.
Utility fog was a further development that blurred the boundaries between virch and r/l. A virchworld could actually be represented in realtime and realspace through utility fog and nano.
The Interplanetary Dark Age meant that the datasphere no longer expanded, as isolated colonies retreated into themselves under their protective shield of blue goo. But there was so much to explore even in on-station computronium that a new period of inward focus and development was initiated. Many of the most important developments in knowledge systems and virchcreation dated from this period. It is in part because of this infotech foundation that the First Federation when it emerged was as successful as it was.
The development of more efficient computronium during the later Federation period was another milepost, and this was associated with the second great singularity and the emergence of new ai that were as far above the federation hyperturings as those ai were above the humans. Whole new realms of infotech and virchuniverses appeared.

Sometimes known as apatophobia, falsuphobia is often mistakenly called virchophobia by the uninformed. However, the two phobias are distinct. While virchophobia is the simple fear of being in a virch, falsuphobia is a fear of receiving false sensory information without knowing it. Falsuphobes often avoid virchs, not because they are afraid of the virch itself, but because they fear that they might become tricked into believing that the virch is the real world.

A copy of any sophont entity, which closely resembles the original when first created. However as soon as the copy and the original begin to interact with the environment the copy will diverge from the original, folloing a separate path of develeopment (hence 'fork').
- Friendzines - Text by Tony Jones
A form of electronic media, not entirely unrelated to the madvert, but rather more benevolent, they are a combination of electronic magazine, news source and companion, combining an expert system optimized towards research and information storage with another expert system tooled towards interpersonal interaction with a specific user.

An interference pattern that is encoded by laser beams and read by means of low-power laser beams. This interference pattern can reconstruct a three-dimensional image.

Measurement is via quantum decoherence, which causes the qubit to collapse into a standard binary state of either zero or one.
