Peak Technology and Asymptotic Technology

To avoid confusion about the definition of these terms, both of which are important in alienology, it might be useful to clarify them here. Peak technology is what happens when an alien civilization runs into a problem, and is unable to sustain the growth of its scientific knowledge. Problems might be some catastrophe that causes shortages, like the alien civilization's bad luck to be on a planet with minimal resources, and try as they might to use them sparingly, they run out before they get to a complete knowledge of technology, a point which is called asymptotic technology, and their civilization begins a downturn. Science begins to be forgotten, or becomes unusable. There might be knowledge preserved in some sort of records, but there are too few people around who can learn it, so, as far as the whole society goes, it is forgotten. To use an extreme example, a planet with only agricultural villagers remaining after a golden age is one where peak technology has come and gone, no matter what type of recordings of past scientific knowledge there is locked away in some vault in a cave. 

Problems can arise from external sources, such as the famous example of an asteroid impact which is large enough to cripple the civilization and prevent it from recovering; the population is reduced below the critical mass needed to maintain technology, let alone progress in it. Problems can arise from internal sources, such as if biological terrorism leads to the extinction of a large fraction of the population. There are a host of other examples in each of these categories. An encounter with a passing star, enough to alter the orbit of the alien planet is one; the star does not have to get so close as to throw the planet out of its solar system, just close enough to make the orbit more eccentric, so that the whole land mass is covered with ice during aphelion, and it doesn't melt during perihelion. A supernova sufficiently close could do it. Basalt flooding could do it. Incessant war could do it. The desire of a ruling elite to maintain itself, coupled with a fear of social change due to more technology could do it. Even persistent, extreme affluence might do it. 

When a civilization suffers a problem such as this, not all technology is forgotten. Depending on how severe the collapse is, there might only be agricultural expertise left. Or transportation equipment at some level might be maintained, depending only on whatever original resouces are left plus renewable ones. The general idea is conceptualized as this graph:


There is no need for the curve to be smooth; it could just as well be bumpy at any section of it. The duration of time that the civilization spends near peak technology is a function of its population, the planet's natural resources, and many other factors. The slopes of the two sides might be of the same order, or they might be different: for example, the rise might be quite steep, as technology's rate of change feeds on itself, but the loss of technology can be slowed by the struggle to maintain it as long as possible.

If nothing goes wrong, technology just keeps accumulating until there isn't any more that isn't known. This is a very finite process. Sometimes someone makes a comment that implies that technology keeps accelerating forever, but this has no meaning whatsoever. Knowledge of details, such as how much sand is on some beach on some exo-planet, might be accumulated, but data is not science or technology. Science is a matter of understanding how the universe operates, and there is certainly some data involved in it, but it is largely a matter of theories explaining phenomena, patterns that exist, cause and effect relationships, and other things; in general it is the compaction of the ability to explain things that happen or that exist. The compaction starts with generalization which often grows into quantitative expressions describing almost anything. 

Asymptotic technology speeds up as early theories are found and validated, which allow more general questions to be asked. At some point, all the easy concepts are found, and the remaining ones grow harder and harder to develop. Thus, the curve of technology looks like an exponential during its earliest phases, and then tips over and continues to slow in its rate of progress, towards an asymptote of total understanding. This is a description of the general form of the technology-time curve, which looks like this:



The height of the asymptote is always the same, for every alien civilization. It is complete knowledge of science and technology. This simple fact is critically important for the study of alien civilization, in absentia. The coupling is done by the principle called technological determinism, which says that technology dictates the forms that a civilization can take, and since the asymptotic technology for every civilization is the same, the form of all the different alien civilizations in the galaxy will have very much in common. If we can understand how technology will progress, we will have an important tool for the study of all alien civilizations. 

One aspect of technology that assists in the understanding of its eventual progression is that technology builds upon itself. Different areas of technology do not progress at the same rate, but instead, one area will go slowly until another area has passed some threshold where the second area can facilitate progress in the first. Thus, technology evolves in stages, which means that the forms of societies will also go through stages. The most all-encompassing of these stages might be called grand transformations, and these appear to involve, in approximate sequence, fire-making, wood and stone use, agriculture and husbandry, metal use, fossil fuel use and the industrial consequents, electronics and its end-effect of artificial intelligence, genetics and psychology and then interstellar space flight, if the civilization is up to it.

Each of these stages might take different amounts of time to come to full blooming. It might be possible to understand them all separately, using the same model of asymptotic understanding. Early learning is relatively faster than late learning. This means that the middle portion of alienology, after the planet-building and origination and evolution of life and before interstellar travel, where civilization develops, has some principles that can be used to gain insights. This is one of the fundamental bases of this blog.
