Future of Life Institute (FLI) — 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.

NoteThe claim is largely confirmed: (1) FLI campaign = Asilomar AI Principles ✓, (2) January 2017 timing ✓ (published 11 August 2017, developed at 2017 conference), (3) 23 principles ✓ (all 23 listed), (4) 5,700+ signatories ✓ (source shows 5,720 as of August 2017, which is within the 5,700+ range). However, the claim specifies 'as of 2017-01' (January 2017) but the source's signature count (5,720) is dated 11 August 2017 — a temporal mismatch. The source does not explicitly confirm the three named signatories (Stuart Russell, Elon Musk, Demis Hassabis) in the provided excerpt, though it notes 'You need javascript enabled to view the open letter signers,' suggesting the full list exists but is not shown in the text provided. This makes the specific signatories unverifiable from the given source text.
