Have you used AI to streamline your work or generate a list for you? Have you been fooled by an AI image? The technology we’ve been watching in movies for 20 years is now in our homes, cars, phones, and schools. Artificial intelligence is no longer theoretical. Most people—across industries and age groups—interact with tools like ChatGPT, Claude, or Gemini. Work apps like Zoom now offer AI summaries, and Microsoft and Adobe have generative AI tools built into their products. This widespread exposure has created a shared baseline: AI is useful, real, and improving quickly.
But there’s a critical distinction that’s still not widely understood—digital AI vs. physical AI.
Digital AI:
Intelligence On-screen
Digital AI operates in a purely virtual environment. It processes text, images, and data to:
• Answer questions
• Generate content
• Analyze patterns
• Support decision-making
Its rapid rise wasn’t accidental. Digital AI benefited from a massive, ready-made dataset: human language and images. For decades, we’ve been writing, storing, and digitizing information—emails, documents, books, photos, websites. It’s been trained on the Internet: the largest repository of language and visuals in human history.
Once that data became accessible, AI systems could be trained quickly and at scale.
That’s why digital AI feels like it “appeared overnight.” It was trained “in the cloud” of ever-expanding data centers, allowing for rapid iteration.
Physical AI:
Intelligence in the Real World
Physical AI takes the same foundational technologies as digital, on-screen AI—machine learning and neural networks—and applies them to real-world interactions.
Instead of predicting the next word, physical AI must decide:
• What object am I seeing?
• How do I move around safely?
• How hard should I grip this item?
• What action should I take next?
This introduces massive complexity. Instead of just structured data, physical AI must work within the real, unstructured environment, around people and things that don’t always follow the rules. The real world isn’t just data—it’s dynamic, unpredictable, and only governed by physics.
Physical AI needs to account for the 3D space of dimensions, with sensors, actuators, and an understanding of interactions and their outcomes.
Why Physical AI Is Slower to Scale (for Now)
When we built digital AI systems, we chose the right dataset by only using some parts of the internet. Chatbots were built using mostly social media data; Coding Agents were built using mostly open source code data.
Physical AI also requires special data for real world use cases. The world is extremely complex, and the sensors that “see” it can also be complex. But, this time, we can’t just look on the Internet to “find” it. The sensors we use, the environments in which robots move, and the special situations we have to prepare for have simply not been recorded.
Unlike digital AI, physical AI lacks a rich historical dataset like the Internet. There’s no ready made data set for how humans move through environments, how objects behave under force, or how tasks are physically completed. All the physical data must be created, not just collected.
The same generative tools that you use in digital AI can be applied within a simulated world, using real-world, grounded physics, and the physical AI hardware (robots and sensors) can be built alongside the AI. We don’t always have to wait for a robot to go out into the world, record the data, and bring it back to us – the robot isn’t ready yet! Companies like NVIDIA, Tesla, and Amazon are accelerating this by combining compute power, simulation, and real-world data collection.
At Torc, our autonomous driving system, TorcDrive, is being trained to work in the real world using both real-world data (recorded camera and lidar images of on-road driving) as well as complex simulated images created from those same on-road recordings, simultaneously.
The Key Insight: Same Brain, Different Body
The most important takeaway is this: digital AI and physical AI are built on the same core technology. Digital AI is proving what’s possible and adaptable by humans, and most importantly, helpful. Physical AI extends that capability into the real world. Everything you’ve seen AI do on a screen—learning, adapting, improving—will eventually happen in the physical world.
What This Means for the Freight Industry
For freight, logistics, and operations, digital AI helps companies and people think better … physical AI can help you perform better.
At Torc, physical AI is manifested in our autonomous driving software, TorcDrive, and powered by AV 3.0, on our trucks today, after being trained by millions of hours of real world and simulated scenarios. It’s the realization of the promises of hundreds of years of technology and human invention. We are still in early days of building physical AI but the trajectory is clear. Digital AI and physical AI aren’t separate revolutions. They are one and the same.
Meet Your First Physical AI
A physical AI machine you might be familiar with is the in-house robot vacuum. The simplest vacuum has the most basic sensors to register the world around it. If it bumps into something, the computer registers the bump against the moveable panel and turns the wheels to rotate itself in a different direction. Other more expensive models can use sensors to determine floor material, and then adjust how they clean accordingly.
More Going On Under the Hood
There are robot vacuum models with self-emptying functions, pet sensors, and even self-cleaning controls. One of the newest models introduced at CES 2025 even has a robotic arm to pick up socks. As we transition to a more physical AI world, how physical AI “understands” and interacts with its surroundings is very different “under the hood” (or dust bin, in this analogy). It’s becoming more complex, and smarter, and importantly, more applicable and helpful.
Not All Physical AI Thinks the Same
How different physical AI instances and machines “think” and how they must act on their sensors vary widely. It is critical to keep in mind that systems are running ever-increasing AI models, trained on real world and simulation data, designed to interact with the physical world in more capable ways, far exceeding the scalability (and capability) of the first physical AI technologies.
