AI is rapidly becoming an integral part of the US workplace. And more than 40% of US employees are using artificial intelligence tools at least a few times a year at work, and that rate is nearly double what it was two years ago, according to a new Gallup poll. The poll asked participants how often they use AI in their work role. In 2023, 21% of US employees reported using AI at least a few times per year. That number almost doubled to 40% in the latest polling by Gallup. According to the research, use of AI has slightly decreased among blue-collar workers over the past two years. Just 9% reported using AI a few times per week or more, down from 10% in 2023. That figure is triple for white-collar workers -- with 27% reporting that they used AI a few times per week or more. Gallup found that the industries with the most frequent AI use are technology (50%), professional services (34%) and finance (32%). AI is becoming increasingly vital to the US workplace, but it remains to be seen how companies and corporations will integrate it into their operations. A report by multinational strategy and management consulting firm McKinsey & Co said that whereas 92% of companies plan to increase their AI investments, a scant 1% have deployed AI so that it is "fully integrated into workflows and drives substantial business outcomes." Other notable findings in the Gallup poll include:
