    TLDR

    An attendee at Judea Pearl’s 90th-birthday celebration credits him with two revolutions in AI: a turn toward probability in the 1980s and a systematic approach to identifying cause-and-effect relationships in the 1990s and 2000s. The tribute emphasizes how Pearl’s contributions spanned decades. The attendee also describes a gathering that mixed science, personal tributes and lively political debate, with recorded messages from Nobel laureates and personal acquaintances.

    @zacharyliptonWhat a joy to spend Sunday celebrating the 90th birthday of @yudapearl, a true inspiration and a giant in our field(s). Judea revolutionized AI research twice, first with its probabilistic turn in the 80s (the field had been mired in side quests to develop alternative logics of uncertainty) and again in the 90s/00s with a systematic treatment of causal identification. Judea is a hero for many reasons, not the least of which is his intellectual longevity. His probabilistic turn came in his 40s (and with it the invention of Bayes nets, d-separation, etc) and his second came towards his 60s, including the complete treatment of the do-calculus. So many inspiring people came to pay their tribute, including @DaphneKoller @erichorvitz, with recorded messages sent in by nobel laureates and personal acquaintances alike, all under the careful curation of @eliasbareinboim. Just like @yudapearl, the event could not be contained, with science, tragedy, joy, and raucous political debate sharing the stage (and occasionally wrestling for it). Throughout, I was awed both by Judea’s perseverance (he was once trapped under a bookshelf at 430a because he was still at the office during an earthquake!) and his pursuit of insights so crystalline that they could ripple across the entire canvas of human scholarship. If the development of AI has profited from a generational struggle between the scruffies and the neats, then @yudapearl sits among our greatest neats, and while the scruffies may have the hot hand today, I hope that the next wave of neats (be they humans or machines) will take inspiration from Judea’s life’s work.
