Does Good's 1965 'Speculations Concerning the First Ultraintelligent Machine' define the ultraintelligent machine and 'last invention' verbatim?

The question

claim-ij-good-1965-ultraintelligent-machine-coined-intelligence-explosion attributes to I.J. Good's 1965 paper "Speculations Concerning the First Ultraintelligent Machine" (Advances in Computers, vol. 6) the definition of the ultraintelligent machine as "a machine that can far surpass all the intellectual activities of any man however clever" and the phrase "the last invention that man need ever make." The note currently rests on Tier 4 Wikipedia, not the primary.

Does the 1965 paper contain both phrasings verbatim, and does it present the runaway-design ("intelligence explosion") argument as the note describes?

Why it matters

The note turns on a direct quote and is the setup for the more surprising recantation claim. Per the sourcing floor, a load-bearing quote should rest on Tier 1–2, not an aggregator. The attribution is uncontested, so this is a verification-not-doubt task — but reading the primary lets the note advance past seedling.

What would answer it

• Locate Good 1965, Advances in Computers 6, pp. 31–88 (or a faithful reprint).
• Confirm the two quoted phrases word-for-word and their context.
• Confirm the intelligence-explosion (recursive self-improvement) argument is stated there, not merely attributed later.
• On confirmation, upgrade source_tier/audit_status and consider budding.
