While people in the communications field have good reason to be worried, Microsoft has unveiled a study showing which careers are most and least likely to be affected by generative AI. What it avoided saying directly, though, was whether those careers would vanish in the coming years.

To determine the risk factor, Microsoft analyzed a “dataset of 200k anonymized and privacy-scrubbed conversations between users and Microsoft Bing Copilot” to assess an AI applicability score. The higher the score, the bigger the threat. The jobs most at risk, it found, were those that involve “providing information and assistance, writing, teaching, and advising.”

The study’s not the first to send up a warning flare about those positions, though. What it did that really stood out was look at the jobs that area less likely to be impacted. And healthcare and blue-collar jobs have the best chance of withstanding an AI assault.

Here’s a ranked look at the 20 careers that posted the lowest AI applicability score:

Dredge operatorsBridge and lock tendersWater treatment plant and system operatorsFoundry mold and coremakersRail-track laying and maintenance equipment operatorsPile driver operatorsFloor sanders and finishersOrderliesMotorboat operatorsLogging equipment operatorsPaving, surfacing, and tamping equipment operatorsMaids and housekeeping cleanersRoustabouts (oil and gas)RoofersGas compressor and gas pumping station operatorsHelpers–roofersTire buildersSurgical assistantsMassage therapistsOphthalmic medical technicians

Other jobs that are in the safety zone include industrial truck and tractor operators, highway maintenance workers, dishwashers, automotive glass installers, embalmers and phlebotomists.
