One year ago today, on November 30, 2022, OpenAI released ChatGPT . It's uncommon for a single tech product to create as much global impact as ChatGPT in just one year.

Imagine a computer that can talk to you. Nothing new, right? Those have been around since the 1960s . But ChatGPT, the application that first bought large language models (LLMs) to a wide audience, felt different. It could compose poetry, seemingly understand the context of your questions and your conversation, and help you solve problems. Within a few months, it became the fastest-growing consumer application of all time. And it created a frenzy.

During these 365 days, ChatGPT has broadened the public perception of AI, captured imaginations, attracted critics , and stoked existential angst. It emboldened and reoriented Microsoft, made Google dance , spurred fears of AGI taking over the world, captivated world leaders , prompted attempts at government regulation , helped add words to dictionaries , inspired conferences and copycats , led to a crisis for educators, hyper-charged automated defamation , embarrassed lawyers by hallucinating, prompted lawsuits over training data, and much more.

On Wednesday, OpenAI announced that Sam Altman has officially returned to the ChatGPT-maker as CEO—accompanied by Mira Murati as CTO and Greg Brockman as president—resuming their roles from before the shocking firing of Altman that threw the company into turmoil two weeks ago. Altman says the company did not lose a single employee or customer throughout the crisis.

"I have never been more excited about the future. I am extremely grateful for everyone’s hard work in an unclear and unprecedented situation, and I believe our resilience and spirit set us apart in the industry," wrote Altman in an official OpenAI news release . "I feel so, so good about our probability of success for achieving our mission."

In the statement, Altman formalized plans that have been underway since last week: ex-Salesforce co-CEO Bret Taylor and economist Larry Summers have officially begun their tenure on the "new initial" OpenAI board of directors. Quora CEO Adam D’Angelo is keeping his previous seat on the board. Also on Wednesday, previous board members Tasha McCauley and Helen Toner officially resigned . In addition, a representative from Microsoft (a key OpenAI investor) will have a non-voting observer role on the board of directors.

In late 2020, Huawei was fighting for its survival as a mobile phone maker.

A few months earlier, the Trump administration had hit the Chinese company with crippling sanctions, cutting it off from global semiconductor supply chains.

The sanctions prevented anyone without a permit from making the chips Huawei designed, and the company was struggling to procure new chips to launch more advanced handsets.

In the stretch of a few days, two municipal water facilities that serve more than 2 million residents in parts of Pennsylvania and Texas have reported network security breaches that have hamstrung parts of their business or operational processes.

In response to one of the attacks, the Municipal Water Authority of Aliquippa in western Pennsylvania temporarily shut down a pump providing drinking water from the facility’s treatment plant to the townships of Raccoon and Potter, according to reporting by the Beaver Countian. A photo the Water Authority provided to news outlets showed the front panel of a programmable logic controller—a toaster-sized box often abbreviated as PLC that’s used to automate physical processes inside of industrial settings—that displayed an anti-Israeli message. The PLC bore the logo of the manufacturer Unitronics. A sign above it read “Primary PLC.”

WWS facilities in the cross hairs

The Cybersecurity and Infrastructure Security Administration on Tuesday published an advisory that warned of recent attacks compromising Unitronics PLCs used in Water and Wastewater Systems, which are often abbreviated as WWSes. Although the notice didn’t identify any facilities by name, the account of one hack was almost identical to the one that occurred inside the Aliquippa facility.

On Tuesday, Stability AI launched Stable Diffusion XL Turbo , an AI image-synthesis model that can rapidly generate imagery based on a written prompt. So rapidly, in fact, that the company is billing it as "real-time" image generation, since it can also quickly transform images from a source, such as a webcam , quickly.

SDXL Turbo's primary innovation lies in its ability to produce image outputs in a single step, a significant reduction from the 20–50 steps required by its predecessor. Stability attributes this leap in efficiency to a technique it calls Adversarial Diffusion Distillation (ADD). ADD uses score distillation, where the model learns from existing image-synthesis models, and adversarial loss, which enhances the model's ability to differentiate between real and generated images, improving the realism of the output.

Stability detailed the model's inner workings in a research paper released Tuesday that focuses on the ADD technique. One of the claimed advantages of SDXL Turbo is its similarity to Generative Adversarial Networks (GANs), especially in producing single-step image outputs.

On Tuesday, Amazon unveiled Amazon Q , an AI chatbot similar to ChatGPT that is tailored for corporate environments. Developed by Amazon Web Services (AWS), Q is designed to assist employees with tasks like summarizing documents, managing internal support tickets, and providing policy guidance, differentiating itself from consumer-focused chatbots. It also serves as a programming assistant.

According to The New York Times , the name "Q" is a play on the word “question" and a reference to the character Q in the James Bond novels, who makes helpful tools. (And there's apparently a little bit of Q from Star Trek: The Next Generation thrown in, although hopefully the new bot won't cause mischief on that scale.)

Amazon Q's launch positions it against existing corporate AI tools like Microsoft's Copilot , Google's Duet AI , and ChatGPT Enterprise . Unlike some of its competitors, Amazon Q isn't built on a singular AI large language model (LLM). Instead, it uses a platform called Bedrock, integrating multiple AI systems, including Amazon's Titan and models from Anthropic and Meta .

Apple has repeatedly trumpeted the success of its financial services, a product lineup that now encompasses the Apple Card credit card, high-interest savings accounts, and a buy-now-pay-later service called Apple Pay Later .

But even if those products have proven reasonably popular with consumers, they haven’t been working out for the bank that Apple has partnered with to supply those services. Goldman Sachs’ consumer services have been losing the company billions of dollars, according to reporting from Bloomberg , CNBC , and The New York Times , among others. These losses have been driven in part by a much higher-than-usual loss rate on its credit card loans—meaning that people with Goldman-backed credit cards like the Apple Card are actually making their payments less often than people with credit cards from other banks.

Today, The Wall Street Journal reports that Apple has sent Goldman Sachs a proposal that will end their partnership within the next 12 to 15 months, leaving Apple to find a new backer for its financial products.

Security researchers are tracking what they say is the “mass exploitation” of a security vulnerability that makes it possible to take full control of servers running ownCloud, a widely used open-source filesharing server app.

The vulnerability, which carries the maximum severity rating of 10, makes it possible to obtain passwords and cryptographic keys allowing administrative control of a vulnerable server by sending a simple Web request to a static URL, ownCloud officials warned last week. Within four days of the November 21 disclosure, researchers at security firm Greynoise said , they began observing “mass exploitation” in their honeypot servers, which masqueraded as vulnerable ownCloud servers to track attempts to exploit the vulnerability. The number of IP addresses sending the web requests has slowly risen since then. At the time this post went live on Ars, it had reached 13.

Spraying the Internet

“We're seeing hits to the specific endpoint that exposes sensitive information, which would be considered exploitation,” Glenn Thorpe, senior director of security research & detection engineering at Greynoise, said in an interview on Mastodon. “At the moment, we've seen 13 IPs that are hitting our unadvertised sensors, which indicates that they are pretty much spraying it across the internet to see what hits.”

Anybody who has pulled weeds in a garden knows that it's a tedious task. Scale it up to farm-sized jobs, and it becomes a nightmare. The most efficient industrial alternative, herbicides , have potentially devastating side effects for people, animals, and the environment . So a Swedish company named Ekobot AB has introduced a wheeled robot that can autonomously recognize and pluck weeds from the ground rapidly using metal fingers.

The four-wheeled Ekobot WEAI robot is battery-powered and can operate 10–12 hours a day on one charge. It weighs 600 kg (about 1322 pounds) and has a top speed of 5 km/h (2.5 mph). It's tuned for weeding fields full of onions, beetroots, carrots, or similar vegetables, and it can cover about 10 hectares (about 24.7 acres) in a day. It navigates using GPS RTK and contains safety sensors and vision systems to prevent it from unintentionally bumping into objects or people.

To pinpoint plants it needs to pluck, the Ekobot uses an AI-powered machine vision system trained to identify weeds as it rolls above the farm field. Once the weeds are within its sights, the robot uses a series of metal fingers to quickly dig up and push weeds out of the dirt. Ekobot claims that in trials, its weed-plucking robot allowed farmers to grow onions with 70 percent fewer pesticides. The weed recognition system is key because it keeps the robot from accidentally digging up crops by mistake.
