The super rich don’t burn cash, they sink it into these insane personal submarines

By Nicole Carpenter Published April 28, 2017

Looking to explore the ocean in your own personal submersible? You’ve come to the right place. Submarines aren’t just for researchers and scientists anymore. You can get one, too — if you’re willing to throw down the money. We’ve rounded up the coolest personal submarines available now. The market is full of variety: Luxury submarines designed to launch from super-yachts, high-flying submersibles that aren’t actually submarines, and futuristic vehicles straight out of a Hollywood blockbuster.

The one thing they’ve all got in common is that they’re all very expensive. In fact, some of these submarines cost upwards of seven figures, but if you’re in the market for a personal BatSub for completely impractical purposes, these are the best you can buy.

The Apple Car may be dead, but it became the foundation of Apple Intelligence

A decade of work on a canceled car project reportedly laid the groundwork for Apple Intelligence.

The Apple Car may have never left the garage, but it apparently gave birth to Apple's AI ambitions. According to Bloomberg's Mark Gurman, Apple's canceled autonomous vehicle project, one that consumed more than a decade of work and over $10 billion before being scrapped in 2024, ended up laying the technological foundation for Apple Intelligence. In a rather ironic twist, one of Apple's most expensive failures may also become one of its most important long-term investments.

Researchers hid a prompt injection inside a PNG, and AI fell for it

AI coding assistants like Claude are becoming every developer's favorite coworker. They can review code, explain confusing functions, and even write entire features with a single prompt. But new research suggests that this growing trust could also become their biggest weakness.

A team of security researchers (professor Sudipta Chattopadhyay and researcher Murali Ediga) has demonstrated an unusual attack that doesn't target the AI model directly. Instead, it targets what the AI doesn't pay enough attention to during code reviews. Rather than hiding malicious instructions in lines of code, the researchers tucked them inside an image file. Since many AI review tools treat images as decorative assets rather than as something worth inspecting, the pull request can appear perfectly harmless and sail through the review.

AI has already fallen into the wrong hands and they’re using it to make bombs

Artificial intelligence has quickly become the go-to tool for everything from writing emails and summarizing meetings to helping students study or developers debug code. But the same technology that saves people time can also be misused, and a new report suggests that terrorist organizations are finding ways to do exactly that.

According to a research paper shared with The New York Times ahead of its publication, researchers found evidence that members of Boko Haram have been using popular AI chatbots to support both day-to-day activities and combat-related tasks. Interviews with 27 former members conducted in Nigeria over the past two years suggest that tools such as ChatGPT, Gemini, Claude, Grok, Meta AI, and DeepSeek were used to gather technical information, troubleshoot weapons, and even assist with planning attacks.
