This is attributed via Quote Investigator, a secondary source specializing in
tracing quotations to primary printed pages; the primary book has not been
independently read for this promotion. The prediction did not come true on
its stated timeline and belongs to a small vault cluster of confident,
falsified AI-pioneer forecasts alongside
[[claim-ij-good-1965-ultraintelligent-machine-coined-intelligence-explosion]]
and the disappointments [[claim-lighthill-1973-blamed-combinatorial-explosion|Lighthill later catalogued]].

Its specific significance in this vault is biographical, not just historical:
Simon is the same theorist whose account of expert intuition
([[claim-simon-defines-expert-intuition-as-domain-bound-recognition]]) and
its low-validity failure condition
([[claim-kahneman-klein-2009-intuition-reliable-only-in-high-validity-environments]])
supply the diagnostic used against [[entity-marvin-minsky|Minsky]] & [[entity-seymour-papert|Papert]]'s sterility conjecture in
[[observation-simon-intuition-framework-diagnoses-perceptron-sterility-conjecture]].
This 1960 prediction is Simon's own instance of the same failure mode: a
confident expert judgment about the un-run future of a young field — a
low-validity environment by his own later framework's standard.
