In late 2022, with the unveiling of ChatGPT, artificial intelligence seemed to enter our day-to-day lives all at once. However, a very different kind of AI has been quietly, gradually introduced into our world in ways that will have a far more profound impact than your average chatbot: physical AI. The application of artificial intelligence to real-world assets lies at the heart of the autonomy-based economy taking shape today.

This revolution couldn’t be more important. Global supply chains, energy systems, and critical infrastructure are under unprecedented strain—creating shortages, outages, and delays and contributing to a rising cost of living. Moreover, there are fewer skilled workers available to address these challenges, which further increases operational risk.
The solution is to remove the friction that once prevented us from accessing real-time information across disparate assets and systems and combining it with decades of historical knowledge long trapped in our machines. This now seamless integration of real-time data enriched by deep historical context has unlocked the true potential of physical AI. With this foundation in place, organizations can synthesize information in ways that improve business outcomes, enhance safety, and help close the workforce skills gap.
We’re already starting to see it happen. At oil refineries, advanced algorithms can constantly adjust fuel blends, processing temperatures, and flow rates across dozens of interconnected units, analyzing thousands of variables each second to squeeze every ounce of efficiency from the operation. Plant operators can make the call to boost throughput without compromising safety or quality—unlocking unprecedented levels of productivity.
And thanks to physical AI, a fire safety system can continuously interpret data from heat, smoke, gas, water, and other sensors, spotting anomalies to provide an early warning to protect people and property. When tiny particles that are the earliest signs of combustion are detected, long before smoke is visible to the human eye, the system could identify what digital algorithms indicate is the signature of an early-stage electrical fire and then notify the fire department and building security.
Physical AI can also help upskill workers. For instance, imagine an AI-assisted maintenance system which can walk a newly hired technician through the delicate steps of fixing a malfunctioning furnace, overlaying real-time diagnostics, annotated diagrams, and adaptive instructions on a handheld display. The system could also monitor the technician’s pace and progress, adjusting its instructions, anticipating mistakes, and offering supportive guidance from start to finish.
Unlike traditional automation, physical AI can offer continuous improvement. As the system operates, diagnostic tools see how its many components behave. The AI model analyzes that data and applies what it has “learned” to create a plan for system optimization. Then, with human approval, the system acts on the plan in an ever-upward spiral of reinforcement.
To be sure, this capability comes with a high level of complexity. Physical AI is not plug-and-play. The data it relies upon is often proprietary, and useful only to those who understand the full operation. Plus, the cost of getting it wrong is also much greater. When a freshman college student inserts a chatbot hallucination into an essay as though it is a valid piece of analysis, it can be embarrassing and potentially lead to a lower GPA. That’s serious, but recoverable. A misinterpretation of flow-rate data in a chemical plant could cost millions in lost productivity or even lives if the error forces a cataclysmic failure.
These are difficult challenges that demand rigorous modeling and validation. Outcomes must be certain. Unlike consumer chatbots, these systems must get it right every time. AI engineers often refer to “six nines,” or 99.9999% certainty that you will achieve your desired outcome. But in industrial applications, that’s the floor, not the ceiling.
This is precisely why fears that workers will be erased from the equation are not just overblown, they misunderstand what industrial autonomy requires. Physical AI does not replace human judgment; it relies on it. In each example above—the refinery, the office building, the factory worker—the indispensable catalyst for a better outcome is the human being. It is the worker’s specialized knowledge, contextual understanding, and judgment that must complete the loop. AI can synthesize, analyze, predict, and recommend but human expertise provides meaning, direction, and accountability.
Across every industry today, the world is being rewired to work better with and for people. Today, physical AI is here and is becoming more deeply embedded in the global economy. By design, it will be hard for most people to notice, since there’s no chatbot providing instantly gratifying responses. Instead, physical AI will quietly evolve in partnership with the industrial workforce to create a more efficient, safer, and smarter world.
