To walk into the lion's den once might be considered foolhardy. To do so again after being mauled by the lion? Six years ago I gave a talk at Ted, the world's leading technology and ideas conference. It led to a gruelling lawsuit and a series of consequences that reverberate through my life to this day. And last week I returned. To give another talk that would incorporate some of my experience: a Ted Talk about being sued for giving a Ted Talk, and how the lessons I'd learned from surviving all that were a model for surviving "broligarchy" – a concept I first wrote about in the Observer in July last year: the alignment of Silicon Valley and autocracy, and a kind of power the world has never seen before.

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these enigmas, we take what we know about space, time, gravity, and quantum mechanics and apply it to a place where all of those things simply break down. There is, perhaps, nothing in the universe that challenges the imagination more. Physicists still believe that if they can come up with a coherent explanation for what actually happens in and around singularities, something revelatory will emerge, perhaps a new understanding of what space and time are made of.

For Christians, Easter is a time to remember how Jesus was killed on the cross before returning three days later. But now, around 2,000 years later, the messiah has returned once more - this time as an AI influencer. The AI Jesus chatbot allows you to video call the son of God in real-time from the comfort of your computer. But faithful followers should be warned that there is a fairly major catch. This AI chatbot has been built not only to deliver words of wisdom and comfort, but also to advertise products. Designed as a'satire on spiritual consumerism', the bizarre website's creators say that the AI Jesus will always make sure to suggest a'strangely fitting product'.

Former CIA station chief Dan Hoffman joins'Fox News Live' to discuss Russian President Vladimir Putin's announcement of a ceasefire in Ukraine on Easter Day. Ukrainian President Volodymyr Zelenskyy expressed skepticism over Russian President Vladimir Putin's announcement Saturday that Russia would observe a temporary ceasefire during the Easter holiday. After the announcement, Zelenskyy posted on X that air raid alerts were ringing out across Ukraine, adding that Russian attack drones were detected in the skies. "Shahed drones in our skies reveal Putin's true attitude toward Easter and toward human life," he wrote. The Kremlin on Saturday shared a video in which Putin said, "Guided by humanitarian considerations, today from 18:00 to 00:00, from Sunday to Monday, the Russian side declares an Easter truce.'"

Beijing held what's being called the world's first half-marathon for robots, allowing bipedal bots to compete alongside human runners, and as one might expect, ridiculousness ensued. The robots, which had human operators running with them, for the most part struggled to make it through the course at all, let alone complete the full 13 miles within the four-hour cutoff time. "One fell at the starting line," Bloomberg reports. "Another's head fell off and rolled on the ground. And one collapsed and broke into pieces."

On Saturday, about 12,000 human athletes ran in a half marathon race in Beijing, but most of the attention was on a group of other, unconventional participants: 21 humanoid robots. The event's organizers, which included several branches of Beijing's municipal government, claim it's the first time humans and bipedal robots have run in the same race, though they jogged on separate tracks. Six of the robots successfully finished the course, but they were unable to keep up with the speed of the humans. The fastest robot, Tiangong Ultra, developed by Chinese robotics company UBTech in collaboration with the Beijing Humanoid Robot Innovation Center, finished the race in two hours and 40 minutes after assistants changed its batteries three times and it fell down once. The slowest time allowed for human runners in the race was 3 hours and 10 minutes, and Tiangong Ultra was the only robot that barely qualified for a human participation award.

It's an interesting time to be a long-running science fantasy media property in the streaming TV age. Star Trek is in the grip of an existential crisis as it (wrongly) fears it's too old-aged to be relevant. Star Wars became a battlefield in the culture war and, to duck all future bad faith criticism, gave us The Rise of Skywalker. And then there's Doctor Who, which is somehow managing to plough a 62-year furrow and still fill it with original ideas. This week the Doctor and Belinda go up against a sentient cartoon holding the patrons of a 1950s cinema hostage.

On Monday, a developer using the popular AI-powered code editor Cursor noticed something strange: Switching between machines instantly logged them out, breaking a common workflow for programmers who use multiple devices. When the user contacted Cursor support, an agent named "Sam" told them it was expected behavior under a new policy. But no such policy existed, and Sam was a bot. The AI model made the policy up, sparking a wave of complaints and cancellation threats documented on Hacker News and Reddit. This marks the latest instance of AI confabulations (also called "hallucinations") causing potential business damage.
