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)OrganizationAlignment Research CenterComprehensive 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 OpenAIOrganizationOpenAIComprehensive 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 ..., AnthropicOrganizationAnthropicComprehensive profile of Anthropic, founded in 2021 by seven former OpenAI researchers (Dario and Daniela Amodei, Chris Olah, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish) with early funding..., and DeepMindOrganizationGoogle DeepMindComprehensive overview of DeepMind's history, achievements (AlphaGo, AlphaFold with 200M+ protein structures), and 2023 merger with Google Brain.

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.

Intellectual Evolution and Current Views
Early Period (2016-2019)
- Higher optimism: Alignment seemed more tractable
- IDA focus: Believed iterative amplification could solve core problems
- Less doom: Lower estimates of catastrophic risk

Strategic Disagreements in the Field
Can we learn alignment iteratively?
Paul ChristianoYes, alignment tax should be acceptable, we can catch problems in weaker systems
Prosaic alignment through iterative improvement
Confidence: medium-high
Eliezer YudkowskyNo, sharp capability jumps mean we won't get useful feedback
Deceptive alignment, treacherous turns, alignment is anti-natural
Confidence: high
Jan LeikeYes, but we need to move fast as capabilities advance rapidly
Similar to Paul but more urgency given current pace
Confidence: medium
