Fintech’s 30-Year Cycle – And Whether AI Will Break It

We tend to talk about technology as if it arrives overnight. One moment the world looks one way, the next everything has changed. 

In reality, technological change usually unfolds much more slowly, but this can be difficult to notice if you’re not watching closely. 

A useful way to think about it is a 30-year cycle: roughly 10 years for a technology to emerge, another 10 years to build stability and infrastructure, and a final decade where it matures and genuinely transforms everyday life.

Fintech’s cycle

Fintech is a good illustration of this pattern.

Take the IPO of PayPal in early 2002. At the time, the idea of sending money online felt genuinely new. The early internet was still a slightly clunky place. People were only just becoming comfortable entering card details online, and the idea of moving money digitally without a bank branch involved still felt a little futuristic.

Yet by the time PayPal listed, the real groundwork had already been laid. The 1990s had seen the first wave of experimentation with e-commerce, online banking and digital wallets. What looked like a breakthrough moment in 2002 was really the end of fintech’s emergence phase, not the beginning.

The following decade - the 2000s and early 2010s - was about making it all work reliably and building trust. Payments firms expanded globally, regulators began adapting to digital finance, and consumers gradually became comfortable with the idea that money could move invisibly through the internet.

You could see the cultural shift in everyday behaviour. Online shopping stopped feeling risky. “I’ll just PayPal you” became a normal phrase. The technology slowly faded into the background - which, in many ways, is the ultimate sign it has succeeded.

By the late 2010s, fintech had reached its maturity phase. A moment that captured this shift was when FIS acquired Worldpay in 2019 in a deal worth around $43 billion. Payments technology was no longer a scrappy disruptor. It had become core infrastructure.

Today the results of that three-decade journey are everywhere. We tap our phones on the subway barrier, split restaurant bills instantly, and move money internationally with a few taps. What once felt revolutionary now feels normal. 

But while one technological wave matures, another usually begins.

The disruption from crypto

The launch of Bitcoin in 2009 introduced a radically different idea: a decentralised financial system operating without traditional intermediaries. Over the past decade, that idea has expanded into an ecosystem of digital assets, decentralised finance and programmable money.

Right now, crypto still feels volatile and experimental, so mainstream consumers are still wary. But that is often what the emergence phase of a new technology looks like. The early internet had dot-com bubbles; early fintech had security scares and scepticism about whether people would ever trust online payments.

Is AI following the same pattern?

Which brings us to the newest technological wave: AI. 

At first glance, AI appears to be breaking the traditional 30-year cycle. The speed at which tools like ChatGPT have entered everyday life has been extraordinary. Within a few years, AI systems have gone from niche research tools to something students, lawyers, programmers and marketers use daily.

Models now seem to make leaps and bounds in months, with whole companies and sectors’ values being called into question every time Anthropic posts on X. 

Compared with the gradual rise of fintech, the AI revolution feels closer to a shockwave. 

But the real story may be more familiar than it first appears. The current wave of AI is actually built on decades of groundwork in machine learning and data science. Neural network research stretches back to the 1980s and 1990s, while the breakthroughs that underpin modern generative AI largely took place during the 2010s.

In other words, AI may not be skipping the three-decade cycle - it may simply be further along in it than we realise (though I acknowledge that many of us weren’t following that niche work that closely - so everything now feels like it’s come from nowhere).

If that’s true, the past few years represent the transition from emergence to infrastructure. The next decade may be less about headline-grabbing demos and more about the slower, less glamorous work of integration: embedding AI safely into financial services, healthcare, government and everyday business processes.

And if fintech offers a guide, the real economic transformation will likely come later - once the technology fades into the background and becomes something we barely notice at all.

Technological revolutions rarely happen in a single dramatic moment. They arrive in waves, building slowly before eventually reshaping the landscape.

Fintech followed that path. Crypto may still be early in it. And AI - despite how fast it feels today - may ultimately prove to be riding the same long tide.
