Future of Life Institute — campaign: Asilomar AI Principles (January 2017): 23 principles for beneficial AI development adopted at the Asilomar Conference. 5,700+ signatories including Stuart Russell, Elon Musk, and Demis Hassabis.

Note: The claim is partially confirmed. The source confirms FLI's campaign, the Asilomar AI Principles, the 2017 conference origin, and the signature count (5720 vs claimed 5700+, which is within acceptable range). However, the source text is truncated mid-sentence at principle 20, so the total number of principles (claimed as 23) cannot be verified from this excerpt. The specific signatories (Stuart Russell, Elon Musk, Demis Hassabis) are not mentioned in the provided source text. The date 'as of 2017-01' is slightly inconsistent with the publication date of 'August 11, 2017' shown in the source, though the principles were developed at the 2017 conference.
