Generative AI is raising efficiency for developers and designers but is also increasing after-hours learning and out-of-pocket spending to keep up with new tools, the article says. Some workers test AI tools 10 to 20 hours a week at night and on weekends and pay for subscriptions and training themselves. A survey found 85 percent learn AI outside working hours. Layoffs and hiring shifts are adding pressure, while access to training and tools varies by employer.

When people think of self-driving cars, Tesla or Waymo often come to mind, but the technology’s roots go back to the 1970s. One early test vehicle was developed in Japan in 1977 and drove using rooftop cameras. German research later achieved higher-speed autonomous runs and long-distance tests, including a 1995 Mercedes trip that was 95 percent self-driven at up to 180 kph. U.S. universities and DARPA competitions also pushed progress.
