The revelation that ChatGPT, the astonishing artificial-intelligence chatbot, had been trained on an Nvidia supercomputer spurred one of the largest single-day gains in stock-market history. When the Nasdaq opened on May 25, 2023, Nvidia's value increased by about two hundred billion dollars. A few months earlier, Jensen Huang, Nvidia's C.E.O., had informed investors that Nvidia had sold similar supercomputers to fifty of America's hundred largest companies. By the close of trading, Nvidia was the sixth most valuable corporation on earth, worth more than Walmart and ExxonMobil combined. Huang's business position can be compared to that of Samuel Brannan, the celebrated vender of prospecting supplies in San Francisco in the late eighteen-forties.

Construction technology continues to evolve, including the creation of a variety of infrastructure, including three-dimensional (3D) prints. Now, the world's first 3D-printed steel structure, a'living laboratory' bridge, has been unveiled by a robot in Amsterdam. This pedestrian bridge with smart sensors will replace the old bridge under external restoration for the next two years. The 3D-printed footbridge, which is over four years in the making, is the result of a unique collaboration between MX3D, software company Autodesk, chief engineer Arup, steel giant ArcelorMittal, the City of Amsterdam, and the University of Twente, among others. MX3D made this design possible by turning welding robots with intelligent software into industrial 3D printers.

Soaring over the world's highest buildings and racing a solar-powered car across the desert may not be on your vacation itinerary this summer, but you can still see what such experiences might be like, thanks to the spectacular new IMAX film, "Dream Big: Engineering Our World." The movie takes audiences from Dubai to Australia, while sharing stirring stories about the impact engineers have on society. Narrated by Academy Award winner Jeff Bridges, it celebrates the inspiring work and people behind these engineering feats. Featured footage includes the Great Wall of China and the Golden Gate Bridge, not to mention an underwater robot developed by a team of students from an underprivileged high school in Phoenix. Made up primarily of Mexican immigrants, the robotics team entered its creation in a competition and succeeded against all odds.
