Business pundits trumpet AI as the future for U.S. employment, but a large-scale survey of U.S. workers indicates that more than 32% are already exposed to some form of AI in their jobs. An additional 6% of workers will begin using AI tools for the first time in 2019. Optimized Workforce – a crowd-sourced think tank that studies the intersection of technology and employment – surveyed more than 10,000 U.S. workers to understand the time they spend on specific tasks, the technologies they work with, and the technologies they will deploy next year to help with those tasks. The survey sampled workers from 19 of the 20 Census Bureau NAICS codes and all of the Bureau of Labor Statistics' top-level occupational codes. The findings, released in a report available on the think tank's Web site, titled "AI Opportunity Report 2018: Which Industries Are Investing in AI? Which Ones Should Be?" reveal that AI-enabled document classification and document creation technologies lead all AI penetration and will continue to see strong investment in 2019.
