Why the old rules of technology prediction no longer apply

In 1978, American researcher and scientist Roy Amara was running the Institute for the Future from an unassuming office in Menlo Park, California. He’d spent decades watching new technologies arrive amid world-changing promises, only to see the initial excitement fade while obscuring the slower, deeper shifts that ultimately reshaped entire industries.  

This pattern became known as “Amara’s Law” – the idea that we tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run. And for almost half a century, Amara’s Law held:   

• The Internet went from a military research project to revolutionary promise, to dotcom wreckage, and finally to the infrastructure underneath modern commerce.  

• Mobile computing was dismissed as a niche toy before smartphones became extensions of our bodies.  

• Cloud computing met resistance for years before it became the foundation of global enterprise operations.  

Each technology followed the arc Amara described: a surge of inflated expectations, a valley of disillusionment, and then a long-run transformation that exceeded even the most optimistic early forecasts. Amara’s Law was everything we wanted in a maxim – a definitive truth that was simple, straightforward, and defensible. Moreover, it gave business leaders a reliable framework for calibrating market expectations and their own.   

That framework is no longer sufficient. Amara’s Law assumed that technology advanced along a single-curve model. But the geometry of tech innovation has now forever changed.   

The emergence of convergence

Amara’s Law followed a consistent arc from overestimation through disillusionment to transformation. Leaders could evaluate technologies sequentially, each on their own terms.  

That logic depended on one crucial assumption: that leaders could evaluate technologies more or less one at a time, on their own timelines. That assumption has broken down.   

The technologies with the greatest strategic consequence today – artificial intelligence, quantum computing, synthetic reality, advanced robotics – are not following independent trajectories. They are converging, amplifying one another, and compressing timelines in ways that a single-curve model like Amara’s Law cannot capture.   

We’ve been tracking this convergence for the past decade, beginning with our first Essential Eight megatrends report in 2016. The difference now is not just the scope but the speed with which these technologies arrive, converge, and scale to solve real business challenges.   

AI accelerates quantum error correction. Quantum advances enable new AI architectures. Each breakthrough in one domain shortens the timeline of the next. This “compression effect” is precisely what Amara’s Law was never designed to account for.  

Amy Webb, CEO of the Future Today Strategy Group, made this case at SXSW in March, retiring her eighteen-year-old annual tech trends report and replacing it with a Convergence Outlook report (we also published about convergence back in 2021 and created a video to illustrate the concept). Tracking technologies in isolation, she argued, creates a false sense of predictability. The real shifts happen at the intersections where multiple systems mature simultaneously and begin reshaping business, labor, and daily life together.  

In a time of accelerated innovation and technology convergence, however, patience becomes one of the most expensive decisions a leader can make. The overestimation phase is shorter, and the underestimation phase hits harder.   

Companies that waited for clarity on generative AI through 2023 and 2024 watched early movers build compounding advantages in talent, data infrastructure, and organizational muscle. According to a 2025 Microsoft-sponsored IDC study, early GenAI adopters are realizing nearly 4x the investment per dollar spent.   

“Wait and see” is no longer a viable strategy. The kind of organizational learning necessary to succeed today can only come from running pilots, experimenting, and iterating.   

This requires a shift in mindset – from the false comfort of familiar growth curves to a new way of navigating toward a destination that is still coming into view.  

A new horizon: how we solve for X  

At PwC, we’ve always viewed innovation through a “horizons” lens. Horizon 1 focuses on technologies ready for immediate application. Horizon 2 looks at those approaching maturity. Horizon 3 tracks long-range, potentially disruptive technologies.   

But beyond those three horizons now lies a new uncharted space where disruptive technology, radical uncertainty, and human transformation intersect. We call this Horizon X.  

Horizon X may sit beyond our current line of sight, but that doesn’t make it any less real. Navigating Horizon X requires a broader outlook and a different approach.  

Solving for X is not about tracking specific technologies independently, but rather, as Webb pointed out, about looking for patterns and signals across technologies and industries. We look at how one development impacts or accelerates another, or in some cases, creates something completely new. Case in point: Anybody else have “human brain cells on a computer chip learn to play Doom” on their EmTech Bingo card?   

The most important variables shaping the future are still unknown. But that doesn’t mean we can’t create a path and start living in that future before it arrives. Solving for X emphasizes learning through action and creating prototypes and experiments before markets fully form. This allows leaders to make better-informed, validated decisions about where to move forward and when to hold back.   

The next evolution of Amara’s Law  

Roy Amara didn’t get it wrong. His law still accurately describes our innate human tendencies when presented with shiny new objects and lofty promises.   

Horizon X – how we define it, how we see it, and how we solve for it – is an evolution of Amara’s Law, not a replacement. More importantly, solving for X gives leaders a more effective way to navigate complexity and multidimensional convergence. The leaders who succeed will be the ones comfortable enough to operate without full visibility, disciplined enough to learn before committing, and confident enough to act amid uncertainty.  

Amara was right about how we see technology. The question now is whether we’re ready to see beyond our familiar comfort zones and widen the aperture to a new horizon of possibility and human potential.
