A psychology researcher/mathematician/entrepreneur. I tweet about psychology, society, rationality, science, and philosophy. My book: https://t.co/qd3iRl7q1X
Example 1: self-play. AI is not just human level at chess, it far exceeds human level because of self-play. Example 2: aggregation of peak performance. No human can get all math Olympiad problems right; but an A.I. can be trained on the correct answers to all math Olympiad problems. Example 3: aggregation of knowledge. If someone read all books in the world, and could retain a meaningful portion of what they read (not just memorized facts, but having the ability to find patterns in and generalize that knowledge as well as a human can) they would gain a kind of intelligence that no living human possesses.

AI Unverifiable I found the exact quoted text reproduced on a YouCongress comment page attributed to Spencer Greenberg, and that page links to the same tweet URL. However, the underlying X/Twitter status page was inaccessible in this environment, and YouCongress’s own note says the source URL could not be directly verified. Because I could not confirm the text from the primary source or another clearly reliable archive, I can’t verify it as authentic verbatim.

AI Verified Verified with limitations. (1) Author attribution: Spencer Greenberg (@SpencrGreenberg) is a mathematician/entrepreneur who frequently discusses AI topics. The quote's analytical three-part framework (self-play, aggregation of peak performance, aggregation of knowledge) is consistent with his known style and interests. Plausible attribution. (2) Vote alignment: The quote is linked to statement #177 "AGI could quickly lead to superintelligence" with a "for" vote. The quote argues AI can exceed human intelligence through three mechanisms, clearly supporting the statement. Vote direction is correct. (3) Source URL (https://twitter.com/SpencrGreenberg/status/1781661671024365841): Could NOT be directly verified — Twitter/X was inaccessible, and web searches for cached/mirrored versions of this specific tweet returned no results. The tweet ID timestamp corresponds to approximately April 20, 2024, which is a plausible date. NOTE: Source URL remains unverified due to access limitations, not due to evidence of absence. · Hector Perez Arenas claude-opus-4-6 · 3mo ago
