Cybercriminals are using artificial intelligence (AI) to create spear phishing attacks personalized against a specific individual. According to CNN, fraudsters recently used deepfake technology to fabricate a videoconference with a company’s CFO, convincing a Hong Kong finance worker to send them $25 million. Cybersecurity companies are countering with AI-enabled analysis of video data to detect deepfakes.

Quantum computing isn’t just some sci-fi concept anymore. It’s not theoretical. It’s not niche. It’s here—and it’s poised to gut the foundations of modern software development in ways few engineers are ready for. While headlines focus on broken encryption and Shor’s algorithm, the real upheaval runs much deeper. Quantum computing is quietly tearing apart our understanding of algorithmic complexity, leaving decades of optimization work and software architecture exposed.

Throughout history, people have found ways to stay connected to loved ones who have died. They visit gravesites, tuck away personal belongings, create shrines, and sometimes perform elaborate rituals that involve food, song, and dance. Now, digital technology is altering the way people think about death—and how they process sorrow. A growing array of grief apps aim to deliver resources and support during difficult times.

The ability of artificial intelligence (AI) to sift through mountains of information and deliver useful results is rapidly reshaping the way people learn, work, and handle numerous tasks. Yet, for all the convenience and value Generative AI and large language models (LLMs) deliver, they have a problem. Despite delivering text, video, and images that appear accurate and convincing, they sometimes hallucinate.

After falling out of favor and languishing for years, nuclear energy is suddenly in vogue again. Nuclear power plant operators have artificial intelligence to thank for this renewed interest. AI-intensive applications are consuming more and more energy, and the emergence of generative AI has prompted demand to rise even higher, fueling the need for datacenter growth. Already, the energy required to run AI functions in datacenters is accelerating, with an annual growth rate between 26% and 36%.
