When It Comes to Marriage and Money, Opposites Attract

The person you marry will often change your relationship to money.

We tend to choose our partners based on shared values, in-common traits and other similarities, marriage researchers say. But money-management styles are one case in which opposites do attract, said Jenny Olson, an assistant professor of marketing at Indiana University who studies couples’ financial decision-making.

We are drawn to people who can check and balance our own rigid rules about money, Prof. Olson said. Someone who feels they are too focused on saving and not focused enough on using money to enjoy life might look for a partner who can help them feel more comfortable with an occasional splurge.

Over the decades, however, spouses often grow more alike. The spendthrifts married to the tightwads manage to find some middle ground, learning from one another in the process, said Scott Rick, a marketing professor at the University of Michigan whose studies marital finances.

“The spouses who don’t converge have a harder time and those marriages are probably more fragile and could end in divorce,” Prof. Rick said, referencing his analysis of 1,303 couples, which will be published in a forthcoming book.

This mutual influence along with the built-in financial accountability couples get when they pool their assets are partly why married couples have a financial advantage over their single counterparts, researchers say. The median net worth of married couples 25 to 34 years old was nearly nine times as much as the median net worth of single households in 2019, up from four times as much in 2010, according to research from the Federal Reserve Bank of St. Louis.

When Kristen James, a 33-year-old product manager in Austin, Texas, first started dating her now-husband, Ben, a 35-year-old startup co-founder, she noticed they came to the relationship with different approaches to their finances. Mr. James considered himself much more of a financial risk-taker; Ms. James preferred to manage her money more conservatively.

Instead of their differences erupting in conflict, Ms. James said her husband’s approach had a positive influence. After talking it over as a couple, Ms. James made the leap to change her career, moving into the technology industry and ultimately earning a higher salary as a result. Without her husband’s encouragement, she said she wouldn’t have felt secure making such a huge life change.

“He said, ‘You’re worth far more than what you’re making,’ and he pushed me to take on more risk and challenge myself in different ways,” she said.

Couples who communicate about the differences in their financial beliefs are better able to make decisions together, as tedious as that practice may initially feel, said Matt Lundquist, a psychotherapist and the clinical director of Tribeca Therapy, a psychotherapy practice based in New York.

He points to clients who take a regular weekend trip and have made it a habit to use the driving time to discuss their finances. While the children snooze in the back of the car, the parents review the state of their budgets and check in on progress toward longer-term goals.

Talking as a pair also prevents an imbalance of power in which one partner appoints themselves money manager, said Adrian Ward, a marketing professor at the University of Texas at Austin.

In his own research looking at how couples manage their money, Prof. Ward found that one partner often takes charge of the finances, not because they’re better equipped to do so, but because they have more time for the job. The in-house money manager—whom Prof. Ward calls “the household CFO”—often shuts the other partner out of the decision-making. Sometimes, the other person is relieved, but over time, that partner’s financial literacy suffers.

“Even though it’s hard to make decisions together and we’re both busy, and it would be way easier for one of us to just do it, it’s the best long-term way to care for each other,” he said.

Marcella Mollon-Williams, a behavioural financial adviser based in Bowie, Md., runs a premarital financial counselling session for couples.

The main issue she sees early on in relationships: Couples too often talk about the things one partner wants the other to avoid doing with their money, as opposed to the things they want to do together.

“Talk about the desires money brings, the things you want to accomplish,” she said. “When you start dreaming together, identifying the things money can buy, it’ll become easier. It’s sort of looking ahead and then working backwards.”

To stay on the same page financially, Kristen and Ben James set a monthly family finance meeting. Talking about their goals, reviewing financial allocations and having time to connect on those topics helps them keep their sights trained on the bigger picture, Ms. James said.

When she’s tempted to scroll through Redfin real-estate listings, she relies on her husband to hold her accountable.

“We have each other to say ‘We’re not buying a new house right now’ or ‘We’re not buying a new car right now’—you have that other person to ground you,” she said.

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.”
