The world's fourth-largest company, Google owner Alphabet, has announced a £5bn ($6.8bn) investment in UK artificial intelligence (AI). The funds will support infrastructure and scientific research over the next two years, marking the first in a series of major US investments tied to US President Donald Trump's impending state visit. In an exclusive interview with BBC News, Alphabet's president and chief investment officer, Ruth Porat, expressed confidence in the UK’s potential for pioneering work in advanced science. A $1bn (£735m) data center will also be inaugurated in Hertfordshire, expanding Google's UK operations. Porat highlighted ongoing development in AI, including efforts with London-based DeepMind, which aims to revolutionize scientific research with AI technology. Despite the promise of economic growth, she acknowledged challenges with the UK government's AI Opportunities Plan. As Alphabet's valuation surpasses $3 trillion, this investment reflects a broader trend of increasing US capital in the UK, against a backdrop of rising currency strength and potential changes in interest rates. Alongside technology advancements, discussions surrounding energy consumption in AI facilities remain critical, with commitments to environmental sustainability being emphasized in Google's strategy.
