I'm pretty sure they don't just use it as a bot detector, but to do rate-limiting too. The faster you solve them the more they dump on you so that it will slow you down.

It's a pretty dishonest way to do rate-limiting to be honest.

Submission + - World's Largest Aircraft Goes Supersonic In First Powered Flight (geekwire.com)

Submitted by Anonymous Coward
An anonymous reader writes: Chalk up another milestone for Stratolaunch, the air-launch venture created by the late Microsoft co-founder Paul Allen: The company’s mammoth airplane deployed a winged test vehicle for its first rocket-powered flight. Stratolaunch’s single-use TA-1 test vehicle blazed a trail for future reusable hypersonic test vehicles that are expected to help the U.S. military catch up on one of the frontiers of aerial combat. TA-1 went supersonic, according to Zachary Krevor, Stratolaunch’s president and CEO — but based on his comments, it may not have quite hit the hypersonic standard of five times the speed of sound. "While I can’t share the specific altitude and speed TA-1 reached due to proprietary agreements with our customers, we are pleased to share that in addition to meeting all primary and customer objectives of the flight, we reached high supersonic speeds approaching Mach 5 and collected a great amount of data at an incredible value to our customers,” Krevor said in a news release.

Today’s test flight took place in the skies above California’s Mojave Air and Space Port, where Stratolaunch keeps its twin-fuselage Roc airplane. Roc is the world’s biggest operational aircraft, with a wingspan of 385 feet. It’s designed to serve as a flying launch pad for rocket-powered vehicles like the TA-1 and its successors. The air-launch concept makes it possible for launch missions to be flown from any airport with a runway that’s big enough to accommodate Roc. It’s similar to the concept that was used back in 2004 to win the $10 million Ansari X Prize for private spaceflight with financial backing from Paul Allen. [...] This flight was the 14th test mission for Roc, coming after an unpowered separation test of its TA-0 vehicle and two captive-carry test flights for TA-1. Today’s test also marked the first in-flight use of Ursa Major’s Hadley rocket engine. The primary test objectives included a safe release of TA-1, engine ignition, acceleration, sustained climb in altitude and a controlled splashdown into the Pacific.

Here's a chemical weapons example: Dual use of artificial-intelligence-powered drug discovery. You take a model designed to minimize harm and then flip the sign on the objective function. So it's not too implausible.

It wouldn't be an LLM, but there's lots of machine learning stuff that isn't based on LLMs.

As long as the fusion reactor can recover reasonably cheaply and quickly, then using inherently unreliable AI to improve the odds is fine.

Neural networks used for control can be made more reliable by imposing constraints on the solution, as well. There's been some work on neural network-based drone control that uses Lipschitz regularization to keep the drones from crashing, like Neural Lander.

Submission + - Study finds anti-piracy messages backfire, especially for men (phys.org) 1

jbmartin6 writes: Threatening messages aimed to prevent digital piracy have the opposite effect if you're a man, a new study from the University of Portsmouth has found. According to the research, women tend to respond positively to this kind of messaging, but men typically increase their piracy behaviors by 18% From the study's abstract: "One threatening message influences women to reduce their piracy intentions by over 50% and men to increase it by 18%. "

I'm not so sure about the author's attribution of this difference to evolutionary psychology, so looking forward to some educational comments on that.
