Technological Scale

Though civilizations progress technologically at different speeds with innovations coming at varying times relative to others, all civilizations demonstrate eventual achievement of certain technological inevitabilities (provided they survive enough Great Filter events to achieve said inevitabilities). The scale evaluates a civilization's technological capability based on these inevitabilities. Technological prowess with certain innovations is evaluated as "rudimentary" or "mastery" based on the socioeconomic and cultural effects of the technology as observed.



"Rudimentary" technology is new and experimental, based on very little knowledge of the subject. The civilization in question is still developing the science behind this particular technology, and may only have one working prototype. As such, "rudimentary" technologies generally have little to no impact on the civilization's society and economy.


"Mastery" over any level of a certain inevitable technology indicates that the civilization in question has a complete or almost complete understanding of the technology and principles behind it, and the social and economic effects of the technology are profound enough that removal of the technology would have a significant negative effect.

Tiers of Mastery

For some clades of technology, there are different tiers of mastery due to the compounding complexity of the associated knowledge and the breadth of the technological applications of said knowledge based on the compounding. Basic constructive engineering, for example, is inevitably achieved much earlier in a civilization's lifespan than advanced constructive engineering because of the compounded knowledge that is required for advanced constructive engineering.
