Are there principles common to technologies?
What really is technology?
How do invention, and innovation, work?
Is there a theory of evolution for technology?
How does the economy arise out of its technologies?

An element consists of other elements (subparts and subassemblies) [complexity]
Elements (techs) can add and lose these ad libitum, recursively
Each new “element” becomes available as a potential part or subpart

“It would seem that the larger theequipment of material culture, thegreater the number of inventions.The more there is to invent with,the greater will be th e number of
inventions. When the existingmaterial culture is small,embracing a stone technique and aknowledge of skins and somewoodwork, the number ofinventions is more limited thanwhen the culture consists of aknowledge of a variety of m etalsand chemicals and the use ofsteam, electricity, and variousmechanical principles such as thescrew, the wheel, the lever, thepiston, belts, pulleys, etc. Thestreet car could not h ave beeninvented from the material cultureexisting at the last glacial period.The discovery of the power ofsteam and the mechanicaltechnology existing at the timemade possible a l arge number ofinventions.”

Technology is autopoietic or self-creating:
– New elements build from existing ones !
– Complication builds from simplicity!

1. Novel element forms as combination from existing elements. Accepted if provides a needed functionality, and is technically and economically viable
2. Novel element replaces techs and components with similar functionality across the collective
3. Adds to the substrate of elements to construct from

4. Novel element generates new needs - for supporting methods and arrangements !- for methods to overcome limitations !- for techs to broaden functionalities !
5. New element destroys replaced technologies’ niches for their dependent technologies
6. The economy adjusts to these steps

“In our universe, matter is arranged in a hierarchy of structures by successive integrations. Whether inanimate or living, the objects found on earth are always organizations or systems. Each system at a given level uses as its ingredients some systems from the simpler level. … The great diversity of vertebrates results from differences in the arrangement, in the number and distribution, of these few [building blocks].”

• Biological: – Darwinian variation and selection !– accumulation of incremental changes!– But … occasional combinations!
• Technological: – Combinatorial evolution!– Abrupt, self-augmenting !– With much Darwinian evolution once a technology exists!
