Race against Sony's champion-beating driver AI in 'Gran Turismo 7'

It's Tuesday, February 21, 2023.

Players will face off against four GT Sophy AI opponents, all with vehicles specced slightly differently. There will be a four-circuit series separated by difficulty, too. The GT Sophy races will only be available until the end of March.

Meanwhile, an amateur Go player beat a highly-ranked AI system after exploiting a weakness discovered by a second computer. By exploiting the flaw, American player Kellin Pelrine defeated the KataGo system decisively, winning 14 of 15 games without further computer help.

It's a rare Go win for humans since AlphaGo's milestone 2016 victory. FAR AI developed a program to probe KataGo for weaknesses. The trick was to create a large "loop" of stones to encircle an opponent's group, then distract the computer by making moves in other areas of the board.

Google Chrome's memory and battery saver modes are rolling out to everyone

The features first emerged in December.

Google Chrome has increasingly become a resource hog over the years, vacuuming up more and more of your system's memory and battery life with reckless abandon. Now, Google is doing something about it. As part of Chrome 110 for Windows, Mac and Chromebook desktops, the company is rolling out memory- and energy-saver modes.
