CORE DEFINITION

Any physically computable process can be simulated by a Turing machine. This means that any logical and physical process in the universe can, in theory, be expressed and computed through algorithms.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

The belief in computability. This is the philosophical cornerstone of digital transformation. If you believe this thesis, then any complex business process, even thought processes, can ultimately be broken down into code. It gives us the ultimate confidence to reconstruct the world with algorithms.

The Church-Turing thesis (not a theorem, but a widely accepted thesis) asserts that all definitions of "effectively computable" (lambda calculus, Turing machines, recursive functions) are equivalent, pointing to the same class of "computable". It delineates the boundaries of what algorithms can do, and also establishes the belief that "all computable processes can be mechanized", becoming the philosophical premise for digitizing and automating real-world processes.

MINIMUM ACTION

In progress 0/5

Practice this model in one real situation:

Believe it is computable: When facing complex processes, first assume "it can be broken down into algorithms".
Model: Abstract the process into computable steps/states.
Digitize: Implement with code and automate execution.
Recognize boundaries: Know that there are undecidable/uncomputable problems (halting problem).
Reconstruct: Continuously reshape business from an algorithmic perspective.
