Imagine a world where doctors can rehearse surgeries before ever making a single incision. Or a technician in one country can guide a repair in another without ever setting foot there.

 That’s the promise of digital twins. In an interview Futurologist, Professor Rocky Scopelliti, unpacked this game-changing technology.

What Is a Digital Twin?

“A digital twin is like a virtual replica of a physical object, a system, or even an entire environment,” explains Rocky. These models use simulations and real-world data to mirror their counterparts. From cars to computer networks, anything can be replicated.

The result? A safer, smarter way to test, analyse, and predict outcomes without real-world consequences. “Digital twins can be used for monitoring, simulation, analysis, or even prediction,” he says. The benefits extend beyond industries, they’re already impacting healthcare in a big way.

Life-Saving Potential in Medicine

One of the most powerful applications of digital twins is in the medical field. “Digital twins can turn surgical procedures into simulations before the operation begins,” Rocky explains. “The surgical team can rehearse and refine their approach, which improves outcomes.” Medical students are also using the technology to practise complex surgeries. Even veterinary science is seeing the benefits.

Built with Powerful Tech

Creating these models takes more than just imagination. According to Rocky, “3D modelling, high-resolution imaging like MRIs or CT scans, and sensor-based technology all come together.”

He also highlights the role of artificial intelligence and machine learning. “These technologies help simulate the behaviour and analyse complex systems in real-time.”

And it’s not just about creating the twin, it’s about making it understandable. “Visualisation and projection technologies are crucial. You need to see what you’re interacting with.”

A Glimpse into the Future

From medical breakthroughs to disaster response, the possibilities are vast. “Let’s say you model New York City to simulate a hurricane,” Rocky says. “You can plan emergency services in advance and protect infrastructure.” He adds, “That same principle applies to bushfires. You can test hundreds of scenarios and optimise your response.”

Everyday Applications

Digital twins aren’t just for hospitals or cities. They can help in your kitchen. “Think about fixing a broken appliance,” Rocky suggests. “A digital twin can guide you through the repair like a virtual instruction manual.”

Furniture assembly? “Instead of reading a booklet, imagine a 3D model walking you through each step.” Manufacturers can also use digital twins to design new car models, test airflow, and refine the product all before production begins.

Global Support, Local Repairs

Digital twins also make remote support easier. “Let’s say there’s a specialist on the other side of the world,” says Rocky. “They can use a digital twin to guide a local technician step by step.” That’s real-time, cross-continental collaboration in action.

But Who Owns Your Digital Twin?

However, digital twins raise big ethical questions like, “If they model my brain or body, do I own that data? Does the hospital? The tech company?”

Rocky admits it’s a grey area. “Who owns the data and the model? These are questions we still need to answer. Ideally, the patient should own it.”

The Bottom Line

Digital twins are more than just cool tech, they’re tools with the power to change how we live, work, and heal. As Rocky puts it: “They let us see, simulate, and solve before problems ever happen.”

And while the tech is impressive, the real breakthroughs will come as we navigate its ethical use and push the limits of what’s possible.

By 2035, Generation Alpha will make up 24% of the global population, having been shaped in a digital world they come with unique perspectives, habits, and aspirations.

Generation Alpha are those born 2010-2024 and are currently aged 15 and under.

To try and see the world from their perspective, we teamed up with Zigazoo to develop an infographic asking Generation Alphas aged 7-15 how they like to learn, what they want to do for jobs and their feelings about the future.

Key insights in this infographic include:

• How Gen Alpha learn, spend and see the future
• Future aspirations
• How they feel about tech
• Optimism for the future

The Largest Generation in History

There are more than 2.1 billion Generation Alphas, making them the largest generation in history.

Gen Alpha prefer to learn by video than by reading, with more than 1 in 3 (36%) turning to videos to learn something new.

When it comes to money, Gen Alphas like to spend a little, and save a little. When asked what they would do with their pocket money, 46 percent took a balanced approach between saving and spending.

Asked about their future career aspirations, many Gen Alphas aspire to be traveling workers: “I want to travel and explore the world while building a business. I don’t want to be stuck in one place.” (Girl, 11)

A third of Gen Alphas are curious about technology. Around 1 in 5 are excited, with an equal number worried. Comments included: “It’s going to be really cool. There might be flying cars, robots building homes and service robots helping people.” (Girl, 11)

“I think there might be some really cool and interesting inventions, but I also think that there might be some that take over the world.” (Boy, 10)

Despite their concerns, 4 out of 10 Gen Alphas feel “very hopeful” about what the future holds: “The future gives you all new chances and you can do almost anything you want! You can try so many new activities and even graduate! It’s like a big treasure hunt!” (Girl, age 10)
