Artificial intelligence can do the work currently performed by nearly 12% of America's workforce, according to a recent study from the Massachusetts Institute of Technology.

The researchers, relying on a metric called the "Iceberg Index" that measures a job's potential to be automated, conclude that AI already has the cognitive and technical capacity to handle a range of tasks in technology, finance, health care and professional services.
