Overview
Section titled “Overview”Paul Christiano is one of the most influential researchers in AI alignment, known for developing concrete, empirically testable approaches to the alignment problem. With a PhD in theoretical computer science from UC Berkeley, he has worked at OpenAI, DeepMind, and founded the Alignment Research Center (ARC)OrganizationARCComprehensive overview of ARC's dual structure (theory research on Eliciting Latent Knowledge problem and systematic dangerous capability evaluations of frontier AI models), documenting their high ...Quality: 43/100.
Christiano pioneered the “prosaic alignment” approach—aligning AI without requiring exotic theoretical breakthroughs. His current risk assessment places ~10-20% probability on existential risk from AI this century, with AGI arrival in the 2030s-2040s. His work has directly influenced alignment research programs at major labs including OpenAILabOpenAIComprehensive organizational profile of OpenAI documenting evolution from 2015 non-profit to commercial AGI developer, with detailed analysis of governance crisis, safety researcher exodus (75% of ...Quality: 46/100, AnthropicLabAnthropicComprehensive profile of Anthropic tracking its rapid commercial growth (from $1B to $7B annualized revenue in 2025, 42% enterprise coding market share) alongside safety research (Constitutional AI...Quality: 51/100, and DeepMindLabGoogle DeepMindComprehensive overview of DeepMind's history, achievements (AlphaGo, AlphaFold with 200M+ protein structures), and 2023 merger with Google Brain.

Section titled “Iterated Amplification and Distillation (IDA)”Published in “Supervising strong learners by amplifying weak experts”↗📄 paper★★★☆☆arXivIterated Distillation and AmplificationPaul Christiano, Buck Shlegeris, Dario Amodei (2018)Source ↗Notes (2018):
| Component | Description | Status |
|---|---|---|
| Human + AI Collaboration | Human overseer works with AI assistant on complex tasks | Tested at scale by OpenAI↗🔗 web★★★★☆OpenAIOpenAISource ↗Notes |
| Distillation | Extract human+AI behavior into standalone AI system | Standard ML technique |
| Iteration | Repeat process with increasingly capable systems | Theoretical framework |
| Bootstrapping | Build aligned AGI from aligned weak systems | Core theoretical hope |
Key insight: If we can align a weak system and use it to help align slightly stronger systems, we can bootstrap to aligned AGI without solving the full problem directly.

Strategic Disagreements in the Field
Section titled “Strategic Disagreements in the Field”Can we learn alignment iteratively? (3 perspectives)
Unknown
Yes, alignment tax should be acceptable, we can catch problems in weaker systems
Unknown
High confidence
No, sharp capability jumps mean we won't get useful feedback
Unknown
Medium confidence
Yes, but we need to move fast as capabilities advance rapidly
