Artificial intelligence and outsourcing are rapidly reshaping the workforce, forcing employers and employees alike to ask a pressing question about the future of work: Which jobs are safe, and which are at risk?

While some roles remain difficult to automate due to regulation, trust or sheer physical complexity, others — what Andrew Gadomski, a managing director at Aspen Analytics and expert in the use of AI in employment and workplace planning, classifies as “knowledge work” — are significantly more vulnerable to automation and less resistant to AI.

Some roles remain highly insulated from AI and automation simply because they can’t be fully replicated by machines, or because society won’t yet allow it. As Marc Cenedella, the founder of Ladders, Inc., a digital job board connecting job seekers with employers, puts it: the jobs least likely to be automated are the ones “that require judgment or taste.” Roles that require empathy, judgement and physical skills will remain resistant to AI.

Take public service and emergency response, for instance. As Gadomski explains, “I always tell my daughter, you can always be a Coast Guard rescue swimmer, you can always be a firefighter.” These jobs require dexterity, quick decision-making and physical exertion — areas where robotics still face barriers of cost, trust and reliability.
