Study: 90% of US work hours lack AI benchmark coverage

A study mapped 923 O*NET occupations to existing AI benchmarks and found only 208 occupations have a task covered by at least five benchmark prompts, with six of 22 job families entirely uncovered. It estimates about 90% of US working hours are spent on tasks with little or no benchmark coverage, skewing toward large labor markets like lawyers while neglecting legal secretaries and similar mid-income knowledge jobs.
