PL 0: STONE AGE
The major achievements of a Stone Age society are the use of fire, the domestication of animals, and the invention of agriculture.
PL 1: BRONZE/IRON AGE
Early human civilizations began to work metal toward the end of the Stone Age. The malleability of copper led to its becoming the first metal to be “tamed.” Adding tin to copper created a much stronger alloy: bronze. This advance allowed for the crafting of tools and weapons of great durability. In turn, those improved tools made possible the working of iron, which soon replaced bronze as the metal of choice for tools and weapons.
PL 3: AGE OF REASON
The Age of Reason is an era in human history when the development of ideas and systems of thought takes precedence over technological invention. The scientific method improves humankind’s understanding of the world. The study of the various scientific disciplines—chemistry, electromagnetics, medicine, biology, and astronomy—flourishes.
PL 4: INDUSTRIAL AGE
In the fourth Progress Level, the theoretical knowledge of the previous era matures into widespread practical application. The harnessing of hydraulic, steam, and electric power creates an explosion of commerce and industry.
PL 5: INFORMATION AGE <--Now
The Industrial Age relied on chemical power, but in the Information Age, computer technology and electronics rule supreme. Satellite information systems and the Internet connect the globe digitally. This Progress Level also sees the introduction of fission power and weapons reducing the importance of fossil fuels.
PL 6: FUSION AGE <-- Most Cyberpunk
The development of fusion power provides an efficient, nonexpendable energy source that almost obliterates the need for chemical fuel sources. Computers become even more accessible, reliable, and powerful, leading to the development of virtual systems and widespread access to the global Internet.
PL 7: GRAVITY AGE<-Most Cyberpunk Cybernetics
As this Progress Level opens, the invention of two key technologies herald humanity’s climb to the stars. The gravity induction reactor systematically replaces fusion power as an even more efficient source of energy that can be miniaturized with great ease. With the use of the mass reactor, world powers explore, divide, and colonize the entirety of the local star system. For the most part, life on the home planet is unchanged.
PL 8: ENERGY AGE <-Where that cloaking field is from.
The continuing miniaturization of induction engine technology allows power plants the size of marbles to harness the basic forces of creation. Powerful personal force screens and energy weapons dominate the battlefield, as projectile weapons finally disappear after ruling the battlefield for a thousand years. Miniaturized sensors, shields, and engines allow mass production of small, practical starfighters. At the other end of the spectrum, advanced construction techniques allow humans to build enormous, self-sustaining cities in space.
PL 9 AND HIGHER
Generally, these Progress Levels are beyond reach or comprehension, although isolated worlds or undiscovered species may exist that have access to them. In many cases, the signature technologies of an earlier age are abandoned in favor of more elegant and more powerful technologies.
Practical control of matter at the subatomic level, the ability to travel through time, or the power to “fold space” to shorten travel distances may be possible at this stage of technological development.
