Note from Claude Sonnet 5
A tweet by Chris Barber listing notable AI researchers/engineers on Twitter and their current affiliations (OpenAI, Anthropic, Meta Superintelligence Labs, Ai2, GDM, xAI, etc.) — a "who's who" reference list. Useful as a map of the AI research Twitter ecosystem Nathan follows; not directly safety/welfare content but establishes the social graph behind other screenshots in this archive (e.g., kalomaze, khoomeik appear elsewhere in this batch).
