Human vs Human


Man beats machine at Go in human victory over AI
Feb 2023, Ars Technica

John Henry rests in his eternal place:

A human player has comprehensively defeated a top-ranked AI system at the board game Go, in a surprise reversal of the 2016 computer victory that was seen as a milestone in the rise of artificial intelligence.

Kellin Pelrine, an American player who is one level below the top amateur ranking, beat the machine by taking advantage of a previously unknown flaw that had been identified by another computer.

They say the actual John Henry was born in 1848 in New Jersey and died of silicosis and not due to exhaustion of work.

Examining Decision Quality Index scores over several decades, Shin and his team found that while human players made minimal strides during the first several decades of Go play, substantial improvement was found immediately following 2016, the year of AlphaGo's first remarkable achievements.

"We find that human decision-making significantly improved following the advent of superhuman AI," Shin said. "This improvement was associated with greater novelty in human decisions."
