Can Light Solve AI’s Energy Bottleneck? by Nick New

William Attardi on June 12, 2026

The increasing energy requirements to power AI is unsustainable, with concerns also growing about the environmental damage that supplying such energy could cause. We are now at an inflection point. Traditional electrical data transfer methods are reaching their limits, with NVIDIA showing its hand by recently investing $4 billion in two photonics companies, Coherent Corp. and Lumentum. NVIDIA is betting on a future where data is transmitted via light (photons) rather than electricity.  Photonics can be integrated directly onto silicon chips to enable scalability and efficiency improvements over electricity. The crux of photonics’ efficiency gain is simple: Light travels faster and carries more information, while producing less heat than electrons. This results in dramatically higher compute density, lower power consumption, and superior thermal performance to overcome the limits imposed by the rise of dark silicon on conventional chips.  Can light solve AI’s energy bottleneck? | Laser Focus World

Remembering the Solemn Purpose of Memorial Day

Memorial Day is a federal holiday in the United States observed on the last Monday in May to honor and mourn U.S. military personnel who died while serving in the armed forces. The holiday traces its roots to the years immediately following the American Civil War (1861–1865), which caused massive casualties—roughly 620,000 soldiers dead, about 2% of the U.S. population at the time. Communities across the North and South began spontaneously decorating the graves of fallen soldiers with flowers, wreaths, and flags, a practice that gave rise to the original name: Decoration Day. On May 5, 1868, Major General John A. Logan, commander-in-chief of the Grand Army of the Republic (GAR)—a powerful Union veterans’ organization—issued General Order No. 11. This proclaimed May 30, 1868, as a nationwide “Decoration Day” to honor those who died in the Civil War. After World War I, the holiday expanded to honor all American service members who died in any war, not just the Civil War.  In 1968, Congress passed the Uniform Monday Holiday Act to create more three-day weekends for federal employees. This moved Memorial Day to the last Monday in May, effective in 1971, when it was also officially named “Memorial Day.” As one 1868 quote put it: “That Nation which respects and honors its dead, shall ever be respected and honored itself.”
