The computing revolution investors cannot ignore

For decades, the world’s computing power has quietly expanded at an astonishing pace.

From the first transistor developed at Bell Labs in 1947 to modern processors containing billions and even trillions of transistors, each generation of technology has been faster, smaller and more powerful than the last.

But according to quantum physicist and technology entrepreneur David Reilly, that era of effortless progress is beginning to slow.

Reilly, CEO of Sydney-based Emergence Quantum and Professor of Physics at the University of Sydney, says the computing infrastructure underpinning modern economies is approaching fundamental physical limits.

And that could have enormous implications for finance, artificial intelligence and global investment.

Speaking at an industry event organised by Kanebridge International, Reilly said many critical parts of modern society depend on computing and the infrastructure used to process information.

The slowdown behind the tech boom

For years, the technology industry relied on a steady improvement known as Moore’s Law, where the number of transistors on a chip doubled roughly every two years.

More transistors meant more computing power, allowing faster software, smarter devices and ever-larger data systems.

Today, however, those gains are slowing.

“It feels to me very innate that I’m going to just find that next year there’s going to be another breakthrough,” Reilly said.

“But if you look at the data…there’s a slowing down, a roll off in performance that started some 10, 20 years ago.”

Rather than making chips dramatically faster, manufacturers are now largely increasing computing capacity by packing more transistors onto each processor.

The approach works, but it comes with growing complexity, higher costs and increasing energy demands.

The brute-force race for AI

That challenge is already visible in the massive data centres being built to support artificial intelligence.

In the race to dominate AI, companies are constructing vast computing facilities that consume huge amounts of electricity and water. Reilly described this expansion as a “brute force” approach driven by the global competition to develop advanced AI systems.

Yet the demand for computing power continues to accelerate.

Artificial intelligence, advanced robotics, healthcare research, pharmaceuticals and cybersecurity all require far more processing capacity than today’s systems can easily deliver.

The question now facing the technology sector is whether traditional computing can keep up.

Enter quantum computing

That is where quantum computing enters the conversation.

Unlike conventional computers, which process information using binary switches that represent ones and zeros, quantum computers exploit the unusual behaviour of particles at the atomic scale.

Reilly describes them as a fundamentally different type of machine.

“So a quantum computer is a wave computer,” he said.

Instead of processing information through simple on-off switches, quantum systems can use wave-like properties of particles to process many possible outcomes simultaneously.

Those waves can interact in complex ways, reinforcing correct solutions while cancelling out incorrect ones. In theory, this allows quantum systems to tackle certain types of problems dramatically faster than classical computers.

What it could mean for finance

The concept may sound abstract, but its potential applications are significant.

Quantum computers are expected to transform areas such as materials science, chemical modelling and pharmaceutical development.

They could also help solve complex optimisation problems in logistics, finance and risk management.

For financial institutions in particular, the technology could offer new tools for detecting fraud, analysing market behaviour and optimising portfolios.

But the shift will not happen overnight.

“One message to take away is that quantum is not going to suddenly solve all of your problems,” Reilly said.

Instead, he said quantum systems will likely complement existing computing technologies as part of a broader and more diverse computing ecosystem.

Why data centres may soon “go cold”

One key change already emerging is how computing systems are physically designed.

Many next-generation technologies, including quantum processors, operate far more efficiently at extremely low temperatures. As a result, future data centres may rely heavily on cryogenic cooling systems to manage heat and energy consumption.

Reilly believes that the shift will gradually reshape the computing industry.

“Over the next five years, you’re going to see data centres go cold,” he said.

“And as that happens, they almost drag with them new compute paradigms.”

Emergence Quantum, the company he co-founded, is focused on developing technologies to support that transition, including cryogenic electronics and integrated hardware platforms designed for quantum computing and energy-efficient systems.

A new technological era

For investors and businesses, the technology remains in its early stages. But the scale of global interest is growing rapidly.

Governments, research institutions and technology companies are investing heavily in quantum research, betting it could become a foundational technology for the next generation of computing.

For Reilly, the moment feels similar to earlier technological turning points.

In the 19th century, new discoveries in thermodynamics helped drive the development of steam engines and the Industrial Revolution. In the 20th century, advances in electromagnetism led to radio, television and eventually the internet.

Quantum physics, he suggests, could represent the next chapter in that story.

“Today we have, as a society, in our hands new physics that we’re just beginning to figure out what to do with,” Reilly said.

“But I think it’s an exciting time to be alive and watch what happens over the coming decades.”

Shipping cargo through an Arctic shortcut never made economic sense—until now.

Climate change and war in the Middle East are flipping the math that previously kept ships plying longer routes from Asia to Europe. A Chinese company on Saturday is starting the first regular cargo service to Europe through Arctic waters, seeking to reap the benefits of quicker travel time and less fuel use.

The shipper Sea Legend will dispatch the Dubai Tower from Ningbo, China, to Felixstowe in the U.K. on what it calls the Arctic Express, following a route along Russia’s north coast. The voyage by the vessel, which is capable of carrying 1,740 20-foot containers, is the biggest commercial step in the Arctic since a Maersk containership first completed the route in 2018.

Global warming is a big factor behind the new route, but it is not the only one. Nearly half the Arctic region’s summer ice—an area four times the size of Texas—has melted over five decades, clearing a fairly reliable path in the summer months. Meanwhile, high oil prices and attacks by Houthi rebels in the Red Sea have made the traditional routes costlier and more dangerous.

Beyond that, Beijing has ambitions to play a role in the Arctic’s future, lending a geopolitical dimension to the Chinese company’s shipping route.

Last year Sea Legend completed a trial run from Asia to Europe in a record 20 days. That is roughly half the time of a voyage via Africa’s Cape of Good Hope that many carriers now take because of the Red Sea uncertainty.

Fuel accounts for 70% or more of the costs while at sea, said Alan Murphy, a former Maersk analyst who runs research firm Sea-Intelligence.

Saving fuel by shortening the journey doesn’t automatically make a route profitable. Insurance premiums for the Arctic are 40% higher than the Cape of Good Hope route, said Jonathan Steenberg, an economist at credit insurer Coface. Sea Legend’s Arctic vessels are relatively small. And even after warming, an icebreaker is still sometimes needed to help the cargo ship.

But if the ship can go without an icebreaker, Coface said the Arctic route is now cheaper than a Cape of Good Hope voyage in some circumstances. It estimated that at current oil prices of around $90, the cost of shipping liquid bulk such as liquefied natural gas could drop roughly 33% compared with the Cape of Good Hope route, while dry bulk goods such as cereals would cost about 8% less.

The route is only passable in the summer and fall. Sea Legend plans eight voyages between August and late October, before conditions get too icy.

“It’s not the Suez Canal but it’s a significant number for the Arctic. It shows there is potential,” said Malte Humpert, founder of the U.S.-based Arctic Institute and author of a book on Chinese shipping in the Arctic.

Even in summer, ships have to navigate around dangerous ice floes and deal with rapidly changing weather. By the end of the shipping season in October, the sky is dark most of the time.

A Russian tanker suffered serious damage to its hull while sailing along the Arctic route despite being assisted by an icebreaker, its insurer, AlfaStrakhovanie, said Thursday, adding that it paid out roughly $650,000.

Coface estimates 3.5% of trade among East Asia, Europe and North America will be able to use Arctic routes within the next five years, representing $64 billion in goods.

Last summer, a record 23 cargo ships transited the Northern Sea Route, which hugs Russia’s north coast. That is tiny compared with the Suez Canal, where more than 30 ships transited daily.

Western companies that want to follow in Sea Legend’s path have to navigate treacherous politics. Russia claims sovereignty over the entire Northern Sea Route and permits for ship traffic are issued by its state-controlled nuclear operator, Rosatom.

“Western companies are in a tricky position,” said Humpert of the Arctic Institute. “At what point do they jump back in the water? When does it become economically necessary, and how do you weigh that against environmental risks and the political dimension?”

An alternative Arctic route, the Northwest Passage that connects the Atlantic and Pacific oceans via the Canadian Arctic, is less passable because it is dominated by narrow waterways where ice gets bunched up. The highest number of cargo ships completing the passage in a year was 13, in 2023.

China has declared itself a near-Arctic state despite not having access to Arctic waters. It depends on Russia’s goodwill to use the Northern Sea Route.

“Beijing is concerned that if they don’t establish a significant strategic presence in the Arctic now, it’s going to be more difficult in the future,” said Marc Lanteigne, expert in polar geopolitics at the Arctic University of Norway in Tromsø. However, he said, “China needs to be careful not to give the impression that they are trying to challenge the strategic order in the Arctic.”

Sea Legend didn’t respond to requests for comment.

Any polar venture contributes to China’s quest to master Arctic travel. The country also has three icebreakers and a support vessel currently on a monthslong scientific expedition north of Greenland. Scientific and commercial voyages can yield data about natural resources awaiting below melting ice caps and information for positioning nuclear-armed submarines.
