The AI boom needs radical new chips. Engineers are stepping up to the challenge

For half a century, the exponential increases in computing performance have powered the digital age. These gains were achieved by shrinking the components on computer chips, meaning that each new generation of semiconductor technology has been faster and more efficient than the last. But, with engineers now facing limits to how much further silicon chips can shrink, and ever-increasing demand thanks to the AI boom, chipmakers are having to get creative. What are the technical innovations they hope will keep the world’s AI ambitions on track?
