The idea
With no assumptions, no learner beats any other averaged over all possible worlds — learning works only where a method's built-in bets fit the world it meets.
In practice
Nearest neighbor bet on similarity; the tree on rectangles; the perceptron on one cut; convolution on nearby pixels; attention on computable relevance.
Where people slip
The theorem stands behind every "what does it assume?" this course has asked.
