Connor Leahy — Notable For: CEO of Conjecture; co-founder of EleutherAI; prominent AI safety advocate; testified before UK Parliament and EU on AI risks

Note: The source text confirms three of the four elements in the claim: CEO of Conjecture, co-founder of EleutherAI, and prominent AI safety advocate (with extensive evidence of advocacy activities). However, the source text does not mention testimony before UK Parliament or the EU on AI risks. The excerpt provided does not address this specific claim about parliamentary/EU testimony, making that portion unverifiable from this source. Since the claim is a compound statement with one element unverified, the overall verdict is 'partial'.

Note: The source text confirms three of the four claims: (1) CEO of Conjecture - confirmed, (2) co-founder of EleutherAI - confirmed, (3) prominent AI safety advocate - confirmed through discussion of his warnings about existential risk from AGI and his advocacy work. However, the source excerpt does not mention testimony before UK Parliament or the EU, which is a specific claim that cannot be verified from the provided text. The excerpt appears to be cut off, so this information may exist elsewhere in the full Wikipedia article, but based on the provided source material, this claim is only partially confirmed.
