Nvidia CEO Jensen Huang joined UK Prime Minister Keir Starmer at the London Tech Week event on Monday. The chipmaker boss called the UK "the largest AI ecosystem in the world without its own infrastructure." Echoing this is Rodrigo Liang, CEO and Co-founder of SambaNova Systems who says energy and infrastructure investment is needed to allow AI to scale. "You need to be cost-efficient, you need to be energy efficient, you need to be space efficient," he added. Liang joined Bloomberg's Tom Mackenzie on "Daybreak: Europe."
