"Although it is coming on 18 years since Deep Blue beat Kasparov, humans are still barely fending off computers at shogi, while we retain some breathing room at Go. ... Ten years ago, each doubling of speed was thought to add 50 Elo points to strength. Now the estimate is closer to 30. Under the double-in-2-years version of Moore's Law, using an average of 50 Elo gained per doubling since Kasparov was beaten, one gets 450 Elo over 18 years, which again checks out. To be sure, the gains in computer chess have come from better algorithms, not just speed, and include nonlinear jumps, so Go should not count on a cushion of (25 – 14)*9 = 99 years."
Whatever the cause, the timing is obviously terrible: Plenty of people surely received one of the two consoles as Christmas presents today, while many more gamers would have happily spent the afternoon in front of the TV. In the meantime, both Sony and Microsoft have acknowledged the problem, with Sony issuing a tweet and Microsoft posting a message on its support website: "We're working to address this as quickly as we possibly can," reads its status website. "Thanks for your patience, Xbox members." In an email, a Microsoft spokesperson declined to comment further or say when the company expects to restore service. We've also asked Sony to comment and will update this post if and when it does. The Xbox Live status page says service remains "limited," and the Playstation Network is listed as offline.
