No, I am not interested in developing a powerful brain. All I am after is just a mediocre brain, something like the Brain of the Man in the Street.

"The only real valuable thing is intuition."
"One could say that a man can 'inject' an idea into the machine, and that it will respond to a certain extent and then drop into quiescence, like a piano string struck by a hammer. Another simile would…"
"The human mind is a very complicated machine."
"The isolated man does not develop any intellectual power. It is necessary for him to be immersed in an environment of other men, whose techniques he absorbs during the first twenty years of his life. …"
"The true nature of intelligence is not to be found in the ability to solve problems, but in the ability to ask the right questions."

Understanding this quote
What it means
Turing is deflecting the grandiose framing of artificial intelligence. He argues you don't need to replicate genius to prove machines can think — ordinary human-level cognition is already an astonishing and sufficient benchmark. It's a strategic lowering of the bar: if a machine can match an average person's reasoning, that alone would be revolutionary and philosophically significant.
Relevance to Alan Turing
Turing proposed the Imitation Game — his test for machine intelligence — rooted in this exact philosophy. He wasn't chasing superhuman AI; he wanted to formalize whether machines could pass as ordinarily human. As a mathematician who cracked Enigma through systematic logic rather than intuition, Turing respected the power of methodical, modest competence over flashy brilliance.
The era
In the late 1940s and early 1950s, computing was brand new and AI was pure speculation. Turing was writing against a backdrop of postwar techno-optimism and deep skepticism about machine thought. Critics dismissed the idea entirely; Turing reframed the debate by grounding it in achievable, relatable human standards rather than science-fiction superintelligence.
