Once again on trends and anti-trends

Before this journal provided the first counter examples to TRIZ trends of
progression of technology,
it was assumed that technology progresses in only one direction (of each path):
The authors of this journal have shown that anti-trends exist:
- from monolithic systems to coarsely segmented ones to finely segmented ones to powders (the law of increasing segmentation);
- from static, rigid systems to dynamic, flexible ones, but not the other way around;
- from mono- to bi- and then to poly-system but not vise versa;
- from macro- to micro-level but not from micro- to macro-level;
- from mechanical to hydrolic/pneumatic and then to electrical implementation of a function (but not vise versa);
- human involvement always decreases with progression of technology but not increases;
- segmentation of a system may decrease rather than increase
(G. Filkovsky, 2005);
- dynamic, flexible systems may give way to rigid static ones
(G. Filkovsky, 2006);
- poly-systems may give way to bi-systems and then to mono-systems
(Y. Karasik, 2003);
- implementation of a function may progress from micro- to macro-level
(Y. Karasik, 2006);
- hydrolic/pneumatic implementations of a function may give way to its
mechanical implementation (G. Filkovsky, 2006);
- human involvement may increase with progression of technology rather than decrease (G. Filkovsky, 2006);
It might appear that the theory could be saved by slight modifications:
Unfortunately, there is a further complication.
Along with trends and anti-trends there is progression in other directions.
For example, for mono-bi-poly trend besides anti-trend (poly-bi-mono)
there are also the following additional trends:
- the trends are statistical;
- the direct trends are dominant and anti-trends are recessive and weak;
For all of them there are examples.
- from mono- to poly- to bi-systems;
- from bi- to mono- to poly-systems;
- from bi- to poly- to mono-systems.
Trends are not one dimensional lines with two possible directions of progression.
They are rather multi-dimensional surfaces with multiple directions of progressions possible at any point in time.
That is why the correct way to model trends is to present them in the form of
"the trees of evolution".
