Adult children across the United States are increasingly reporting that their aging parents have developed what looks remarkably like the smartphone addiction [non-paywalled source] typically associated with teenagers, a phenomenon The Atlantic's Charlie Warzel has dubbed "phone-based retirement." A 2019 Pew Research Center study found people 60 and older spend more than half their daily leisure time -- four hours and 16 minutes -- in front of screens. Nielsen reported this year that adults 65 and up watch YouTube on their TVs nearly twice as much as they did two years ago. 40% of adults aged 59 to 77 reported feeling anxious without device access in a 2,000-person survey. Ipsit Vahia, chief of geriatric psychiatry at Mass General Brigham's McLean Hospital, cautioned against treating all older adults as a monolithic group. The COVID-19 pandemic drove significant tech adoption among seniors as Zoom became essential for family gatherings, church services, and telehealth. Some research suggests device use may be linked to better cognitive function for people over 50, and Vahia noted that technology use in older adults appears to protect them from isolation and loneliness -- the opposite of its effect on teenagers.

The weight of AI server racks has reached a point where legacy data centers cannot accommodate them even with significant retrofitting efforts, The Verge reports. Chris Brown, chief technical officer at Uptime Institute, said most retrofitting attempts would require "bulldozing the building and starting over from scratch." AI racks are projected to reach 5,000 pounds compared to the 400 to 600 pounds that racks weighed three decades ago. The dramatic increase stems from hundreds to 1,000 GPUs packed densely into each rack alongside memory chips and liquid cooling systems that can add substantial weight. AI workloads now consume up to 350 kilowatts per rack, 35 times the 10 kilowatts that traditional computer chip workloads averaged a decade ago. Legacy data centers with raised floors typically max out at around 1,250 pounds per square foot for static loads. Chris McLean, president of Critical Facility Group, said that rack heights have grown from 6 feet to 9 feet over nearly two decades, creating problems with doorframes and freight elevators in older buildings.

The glasses-shaped face computers that tech companies have been building for years now face an identity crisis, and their makers can't agree on what to call them. Meta has asked a journalist to refer to its Ray-Ban glasses as "AI glasses" to distinguish them from Google Glass. Google, whose Project Aura is a collaboration with Xreal, calls the product "wired XR glasses" because the company views it as more aligned with headsets in a glasses form factor. Xreal's CEO Chi Xu laughed when asked about Aura's category and said the company will call all its products "AR glasses." Research firms aren't aligned either. Gartner defines smart glasses as camera- and display-free devices with Bluetooth and AI. Counterpoint Research said smart glasses without see-through displays drive volumes in the smart eyewear category. IDC uses a broader definition that includes anything glasses-shaped.
