CORE DEFINITION

The total amount of human knowledge is doubling at an ever-increasing rate. In 1900, it doubled every 100 years; by 1945, every 25 years; now it may double every 12 hours.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Lifelong learning: The shelf life of academic credentials is shrinking rapidly. Knowledge learned in university may be outdated by graduation. The only survival skill is 'learning how to learn' (meta-learning).

Anchor fast decisions

Knowledge production exhibits compounding and network effects: existing knowledge serves as input for new knowledge, and advances in communication and computation accelerate output, so the doubling period continuously shortens, showing exponential or even super-exponential growth.

Vavilovian Mimicry

Vavilovian mimicry (also known as crop mimicry or weed mimicry) is a form of plant mimicry in which weeds, through generations of artificial selection, acquire one or more traits that resemble those of a cultivated crop. This mimicry was discovered and named by the prominent Russian plant geneticist Nikolai Ivanovich Vavilov (founder of the theory of centers of origin of cultivated plants). Selection against weeds can occur during both the seedling and mature stages, and can also involve separating their seeds from crop seeds through winnowing, or both.
