The Oura Ring 4 is a competitive sleep tracker, with insights into sleep efficiency, restfulness, readiness, latency, and more. I’ve been using the Oura Ring for a while now, and it has not only given me deeper insight into my sleep but also supplements those data points with explanations behind the numbers. Oura claims to accurately track sleep cycles, total sleep time, resting heart rate, heart rate variability, and movement.These features have been enhanced with the rollout of the fourth-generation Oura Ring, which hit the market in October. The Oura Ring 4 has smart sensors that allow more accurate and continuous data capture. It’s also more comfortable than the Oura Ring 3 and has flattened sensors that make it easier to wear over time.Also: I tested the Oura Ring 4 for weeks. Here’s why it’s the best health tracker right nowEvery morning, I get a sleep score for last night’s sleep and view my heart rate, sleep efficiency, and suggested bedtime range for the day. The sleep score helps me understand my energy levels for the day and my activity bandwidth, like whether I should exercise or rest. The Oura Ring can also detect the shortest of naps and factor those into the sleep score for the day. Plus, the sleep tab on the app offers information on sleep efficiency, restfulness, REM, deep sleep, latency, and timing, so you can dig deep and go beyond viewing just a sleep score and your time spent in bed.As if there aren’t enough sleep-friendly features in the Oura Ring, Oura also unveiled a body clock feature that teaches users more about circadian rhythms and the body clock. The feature measures sleep chronotype, calculated by body temperature, sleep-wake cycle, and physical activity. Through this data, I learned that I’m most productive during the late morning.Also: The best smart ringsThe battery life is excellent. It charges quickly and stays charged for around five to six days. Oura says the new generation’s battery life lasts eight days, but I haven’t found that to be the case in my testing. The one downside to the ring is the extra $72 you spend on the Oura subscription each year, on top of the $350 you spend on the ring itself.Redditors also agree that the Oura Ring, as a sleep tracker, is worth it. “If you struggle with sleep quality, overtraining, or anything else that affects recovery, I’d say it’s worth it,” one user wrote in a thread. However, one Best Buy reviewer noted that the ring doesn’t offer half sizes, which could be an issue if your fingers swell.Oura Ring Gen 4 specs: Up to 8 days battery life | Sleep cycles | Bluetooth | Up to 100m water resistant | Blood oxygen, skin temperature sensor, heart rate monitoring | iOS and Android compatible More

Ever since generative AI exploded in popularity, one of the major concerns has been how it will impact jobs and replace the human workforce. That fear is only heightened with the mention of AI agents, as they can carry out tasks for humans without even needing constant human prompting or supervision, eliminating the need for humans to perform specific tasks even further.However, just because an AI agent can carry out some tasks doesn’t necessarily mean it can do all of them. As mentioned above, there are critical business operations that an AI agent cannot replace, such as face-to-face interactions with clients or higher-level tasks involving problem-solving, experience, or creativity.Also: Want to win in the age of AI? You can either build it or build your business with itIn fact, according to LaMoreaux, AI agents may amplify the need for humans in some areas.”With AI and generative AI, domain expertise becomes more important, not less important,” said LaMoreaux. “The AI agents already know the basics, so when things need to get unique, then routed to humans, it’s going to be higher-order questions and problems.”Building on this idea, Elsakr also highlighted that the models themselves don’t have ideas. As a result, it is imperative that humans come up with better ideas now and spend real time implementing ideas that matter.Another concern about AI agents is that they are entirely autonomous and, as a result, can handle important business tasks and data without the need for direct human supervision guiding their every step, leaving room for bias, privacy concerns, and error.However, it is important to remember that AI agents can be tailored to fit the specific company’s needs. They are given the authority to access only information the company is willing to share and can only perform actions they are specifically granted the authority to do. Ultimately, these tasks should be carefully chosen to ensure they align with the company’s needs and values.Also: This new AI benchmark measures how much models lieFor example, LaMoreaux explained IBM uses an agent to help match candidates to potential job roles, as opposed to using an AI agent for selection to weed out applications. Even though other companies use AI agents for filtering and selecting processes, there is a risk of inviting AI bias and not selecting people with different educational backgrounds, which doesn’t align with the company culture.This keeps the company in control of how AI agents behave. As a result, even though the technology is autonomous, users can find comfort in knowing it won’t act in ways it hasn’t been permitted to.  More

Kerry Wan/ZDNETDid you know that whenever you turn on your smart TV, you invite an unseen guest to watch it with you? These days, most popular TV models utilize automatic content recognition (ACR), a form of ad surveillance technology that gathers information about everything you watch and transmits it to a centralized database. Manufacturers then use your data to identify your viewing preferences, enabling them to deliver highly targeted ads.Also: I changed these 6 TV settings to drastically speed up its performance (and why they work)What’s the incentive behind this invasive technology? According to market research firm eMarketer, in 2022, advertisers spent an estimated $18.6 billion on smart TV ads, and those numbers are only going up.To understand how ACR works, imagine a constant, real-time Shazam-like service running in the background while your TV is on. It identifies content displayed on your screen, including programs from cable TV boxes, streaming services, or gaming consoles. ACR does this by capturing continuous screenshots and cross-referencing them with a vast database of media content and advertisements. More
