It won't be easy for Big Tech companies to win the hearts and minds of Americans who are angered about massive artificial intelligence data centers sprouting up in their neighborhoods, straining electricity grids and drawing on local reservoirs.

Aran Nayebi jokes that his robot vacuum has a bigger brain than his two cats. But while the vacuum can only follow a preset path, Zoe and Shira leap, play and investigate the house with real autonomy.

For an increasing number of Americans, a new kind of co-worker is making their work easier.

Defense Secretary Pete Hegseth said Monday that Elon Musk's artificial intelligence chatbot Grok will join Google's generative AI engine in operating inside the Pentagon network, as part of a broader push to feed as much of the military's data as possible into the developing technology.

Artificial intelligence (AI) is increasingly used to analyze medical images, materials data and scientific measurements, but many systems struggle when real-world data do not match ideal conditions. Measurements collected from different instruments, experiments or simulations often vary widely in resolution, noise and reliability. Traditional machine-learning models typically assume those differences are negligible—an assumption that can limit accuracy and trustworthiness.
