When the system detects small cracks in road surfaces, it promptly seals them. The United States will suffer in the race to command the development of artificial intelligence (AI) if production and manufacture of semiconductor chips and processors remain offshore, according to an industry expert. "If you're not making things and all you're doing is designing the software, and maybe designing the chips, but they're completely built and packaged elsewhere, you don't end up innovating as much when you literally have people's hands making some of these technologies," Jonathan Klamkin, CEO of semiconductor company Aeluma, told Fox News Digital. "You innovate across the supply chain, you'll innovate the manufacturing equipment that's used in the pads, you'll innovate how to operate the pads, you'll innovate the design of the chips," Klamkin said. "The U.S. needs to be vertically integrated in semiconductors. We can't just design the chips and write the software code."

When it comes to handbags, these days there are almost as many ways to jazz up your existing bag as there are new designs. In Selfridges' vast accessories hall in London, you can buy a clip-on set of metal flowers from Louis Vuitton, multi-coloured jangling robots from Prada, and leather tassels at Ted Baker. What customers want, it seems, is a way to stamp a bit of individuality on their purchases. And one new counter at Selfridges will let you go a stage further. At Mon Purse, an Australian brand, you are handed an iPad and samples of leathers, and given the chance to design your own handbag.
