Thought I'd ripp some of the text from D23 and drop it in here, some parts still needs some additions before they will make sense, the history section for example is only partly developed.
Computers have steadily grown in power while still diminishing in size. By the time of D23 computers in common usage are typically no bigger than a wrist watch, advancements in neural systems and memory emulation technology make the processing capability so powerful that to try to compare 20th century systems with what exists today is simply meaningless. Storage capacity and processing power are interchangeable and even the smallest computer is run by a dedicated master level AI.
The Internet still exists in a form, though it has been completely redesigned and rebuilt in the last century. These days it incorporates all forms of media communications from Conferencing (video / voice communication), Passive Entertainment Media (former TV and Radio entertainment) and Active Participation Media (former online gaming, interactive and participation media, and conferencing chambers).
The gate has been the single greatest advance in recorded human history. It opened the way to the modern world and made necessary certain advances in energy production and computer technology, and produced a number of by-product technologies. Most fundamentally the gate permits people and cargo to enter at one and exit at the other with a near instant transition period. This essentially provides faster-than-light transportation across any distance, provided that there is a gate on the other end.
While the gate permits faster-than-light travel it cannot be used to send anything but the most limited communications. The gates can only be opened for a period of up to a minute, then they collapse, establishing communication through this sub-space dimension of the gate is thus extremely limited, making human couriers the most effective manner of moving large amounts of data (encoded on optical wafers) over interplanetary distances.
The development of industrial process nanobiotic cultures underpinned the 2060’s recycling boom. Vast recycling plants were built to house nano-culture vats. Almost any type of waste could be dropped into the vat to be disassembled and organised into new chemical resources and all at the fraction of the cost of traditional recycling. Many of the ancient landfill sites were excavated and their rich resources reclaimed.
Recycling nano-cultures were the first and the simplest of the industrial process applications for nanotechnology. Manufacturing applications were not far behind as more exact control of ‘worker nanites’ was developed with the introduction of ‘director nanites’ that could be used to switch workers on and off or adjust their assigned duties. First relatively simple manufacturing plans were devised permitting the production of various textile fibres, then the first nano-circuits were constructed in this industrial vat environment, ultimately certain specialised fibers that can only be manufactured by nano-processes began enter circulation.
Medicine has advanced in leaps and bounds, particularly with the advent nanobiotic cultures. The word nanotechnology conjures and image of microscopic robots performing complex tasks in the repairing of cells and bodily damage. The truth might seam considerably less high tech, nanobiotic cultures have more in common with protein chemistry than with robotics, each tiny ‘worker nanite’ is formed from plastic fragments with specific sugar and fat molecules attached to ensure that the correct conformation is adopted. Other ‘director nanites’ can act as keys to trigger confirmation change that in turn changes the function of the ‘worker’. The typical nanite has an operational life span of anything up to 15 minutes and cannot survive outside normal living body conditions, unless suspended in culture.
A complex medical situation would require a specific course of nanobiotic injections to ensure that tissue is repaired in the correct order and control over worker functionality must be monitored by the careful application of directors. The nanites are themselves grown in industrial cultures and suspended in an inert solution to await activation upon injection.
Military weapons are based on electromagnetic acceleration principles, but they no longer fire solid slugs or have ammunition cases to discard. A typical modern military firearm requires a both a battery pack and magnetic liquid reservoir. A small quality of mag-lik is chambered, magnetised and accelerated along the barrel. The mag-lik forms a needle like projectile under the influence of the accelerator mag-fields, the projectile will rip easily though even heavy conventional armour and expand within soft living tissue causing massive internal trauma, the mag-lik itself is by natural by-product of its mercury based structure, poisonous, though not significantly to increase its battlefield performance.
Some modern battlefield weapons still make use of caseless munitions, such as Guided Explosive Munitions (GEMs) this term has been adopted for similar munitions with different payload condiments like Gas, Refractive Pigments, EMP and a host of other warheads in common usage.
Heavier support weapons and artillery are commonly equipped with larger variations on gauss technology some of which are combined with sophisticated Military AI’s that ID and destroy targets as they present themselves. This technology has revolutionised warfare. Air superiority is a thing of the past; the onus is again on ground forces and stealth, vehicles while capable of carrying large support weapons are as easily destroyed as they are identified.
