Turing proposed a test for discussing machine intelligence.
A question about imitation made machine intelligence discussable rather than settled.
The paper proposes an imitation game; it does not claim to build a thinking machine.

Both examine how a conversation with a machine is perceived by people; Weizenbaum documents the impression it creates.
Both concern a public demonstration of machine language behaviour before a human audience.
Both records bear on what counts as evidence of machine thinking.
The 1947 lecture contains arguments Turing set out three years later in the imitation game paper.
The argument denies outright that a behavioural test establishes understanding.
Minds, Brains, and ProgramsThe tournament was billed as the first actual administration of the Turing test, restricted in topic and tenor so that programs had a chance.
