Artificial intelligence experts said it wouldn’t happen in 2016 — even 2030 would be a stretch. But it did.

in South Korea.
Go is an ancient Chinese board game that’s elegantly simple, yet wickedly difficult to master because of the near-infinite number of legal moves on the
board’s 19-by-19 grid. AI researchers have pushed for years to build an algorithm that could handle this complexity and topple human Go champions.
