What Happens When AI Directs Tourists to Places That Don't Exist?

3 months 2 weeks ago
The director of a tour operation remembers two tourists arriving in a rural town in Peru determined to hike alone in the mountains to a sacred canyon recommended by their AI chatbot. But the canyon didn't exists — and a high-altitude hike could be dangerous (especially where cellphone coverage is also spotty). They're part of a BBC report on travellers arriving at their destination "only to find they've been fed incorrect information or steered to a place that only exists in the hard-wired imagination of a robot..." "According to a 2024 survey, 37% of those surveyed who used AI to help plan their travels reported that it could not provide enough information, while around 33% said their AI-generated recommendations included false information." Some examples? - Dana Yao and her husband recently experienced this first-hand. The couple used ChatGPT to plan a romantic hike to the top of Mount Misen on the Japanese island of Itsukushima earlier this year. After exploring the town of Miyajima with no issues, they set off at 15:00 to hike to the montain's summit in time for sunset, exactly as ChatGPT had instructed them. "That's when the problem showed up," said Yao, a creator who runs a blog about traveling in Japan, "[when] we were ready to descend [the mountain via] the ropeway station. ChatGPT said the last ropeway down was at 17:30, but in reality, the ropeway had already closed. So, we were stuck at the mountain top..." - A 2024 BBC article reported that [dedicated travel AI site] Layla briefly told users that there was an Eiffel Tower in Beijing and suggested a marathon route across northern Italy to a British traveller that was entirely unfeasible... - A recent Fast Company article recounted an incident where a couple made the trek to a scenic cable car in Malaysia that they had seen on TikTok, only to find that no such structure existed. The video they'd watched had been entirely AI generated, either to drum up engagement or for some other strange purpose. Rayid Ghani, a distinguished professor in machine learning at Carnegie Melon University, tells them that an AI chatbot "doesn't know the difference between travel advice, directions or recipes. It just knows words. So, it keeps spitting out words that make whatever it's telling you sound realistic..."

Removing 50 Objects from Orbit Would Cut Danger From Space Junk in Half

3 months 2 weeks ago
If we could remove the 50 most concerning pieces of space debris in low-Earth orbit, there'd be a 50% reduction in the overall debris-generating potential, reports Ars Technica. That's according to Darren McKnight, lead author of a paper presented Friday at the International Astronautical Congress in Sydney, which calculated the objects most likely to collide with other fragments and create more debris. (Russia and the Soviet Union lead with 34 objects, followed by China with 10, the U.S. with three, Europe with two, and Japan with one.) Even just the top 10 were removed, the debris-generating potential drops by 30%. "The things left before 2000 are still the majority of the problem," he points out, and "76% of the objects in the top 50 were deposited last century." 88% of the objects are post-mission rocket bodies left behind to hurtle through space. "The bad news is, since January 1, 2024, we've had 26 rocket bodies abandoned in low-Earth orbit that will stay in orbit for more than 25 years," McKnight told Ars... China launched 21 of the 26 hazardous new rocket bodies over the last 21 months, each averaging more than 4 metric tons (8,800 pounds). Two more came from US launchers, one from Russia, one from India, and one from Iran. This trend is likely to continue as China steps up deployment of two megaconstellations — Guowang and Thousand Sails — with thousands of communications satellites in low-Earth orbit. Launches of these constellations began last year. The Guowang and Thousand Sails satellites are relatively small and likely capable of maneuvering out of the way of space debris, although China has not disclosed their exact capabilities. However, most of the rockets used for Guowang and Thousand Sails launches have left their upper stages in orbit. McKnight said nine upper stages China has abandoned after launching Guowang and Thousand Sails satellites will stay in orbit for more than 25 years, violating the international guidelines. It will take hundreds of rockets to fully populate China's two major megaconstellations. The prospect of so much new space debris is worrisome, McKnight said. "In the next few years, if they continue the same trend, they're going to leave well over 100 rocket bodies over the 25-year rule if they continue to deploy these constellations," he said. "So, the trend is not good...." Since 2000, China has accumulated more dead rocket mass in long-lived orbits than the rest of the world combined, according to McKnight. "But now we're at a point where it's actually kind of accelerating in the last two years as these constellations are getting deployed." A deputy head of China's national space agency recently said China is "currently researching" how to remove space debris from orbit, according to the article. ("One of the missions China claims is testing space debris mitigation techniques has docked with multiple spacecraft in orbit, but U.S. officials see it as a military threat. The same basic technologies needed for space debris cleanup — rendezvous and docking systems, robotic arms, and onboard automation — could be used to latch on to an adversary's satellite.")
