Robots and Artificial Intelligence: The Silent Revolution Reshaping the Global Economy
Robotics is advancing at breakneck speed, driven by a demographic crisis and unprecedented technological breakthroughs. Here's why, according to Pictet Asset Management, we are standing at the dawn of a new era of productivity.
Picture a surgeon operating with the millimetre precision of a robotic arm, or a factory running around the clock with no interruptions, no lights, no heating required. Scenarios that just a few years ago seemed like pure science fiction are now operational realities in many parts of the world. And we're only just getting started.
Robotics is going through an extraordinary period of acceleration, fuelled by two powerful forces moving in parallel and reinforcing each other: an increasingly unfavourable global demographic outlook and technological advances — particularly in artificial intelligence — that are fundamentally redefining what it means to be a machine. This is the central argument of an analysis by Anjali Bastianpillai, Senior Product Specialist at Pictet Asset Management, published in April 2026.
The Demographic Problem No Government Can Ignore
The starting point is uncomfortable, but unavoidable: the world is ageing. By 2050, the global share of people aged over 60 is set to double, rising from 11% in 2010 to 22%. In economic terms, this means there will be fewer and fewer active workers to support a growing number of retirees — what economists call the "dependency ratio."
The consequences are direct: a shrinking workforce means lower output, slower growth and reduced competitiveness. It is a structural pressure that no fiscal policy, on its own, can reverse. And this is precisely where technology steps in as a systemic solution, rather than a mere optimisation tool.
AI Changes the Rules of the Game
Robots are nothing new — we have seen them on car assembly lines for decades. But those were rigid machines, programmed to carry out repetitive tasks in controlled environments. What is changing today is their ability to adapt, learn and interact.
Recent advances in machine learning — and in particular the rise of generative artificial intelligence — have transformed the way robots perceive and interpret their surroundings. A next-generation robot can operate in a restaurant just as well as in a logistics warehouse: recognising objects, making real-time decisions and working alongside humans without putting their safety at risk.
According to the Pictet Research Institute, this interplay between demographic pressures and technological innovation is opening a new economic era defined by automation, artificial intelligence and productivity gains on a scale never seen before.
A Measurable Impact on GDP
The numbers speak for themselves. International manufacturing data shows that every increase in robot density contributes approximately 0.4% to annual GDP growth. That is not a negligible figure: at a global scale, and over decades, the cumulative effect is potentially transformative.
Even more striking is the outlook for artificial intelligence. Unlike the revolutionary technologies of the past — from electricity to the internet — AI appears set to sidestep the so-called "J-curve": that long phase in which investment keeps growing without yet producing tangible returns. The AI curve is far steeper on its path to profitability, partly thanks to the experience accumulated during previous waves of digital innovation.
A Market Explosion: From Robotaxis to Humanoids
Demand for robots is growing along two complementary tracks. The first involves substitution robots — machines designed to compensate for labour shortages in highly labour-intensive sectors. The second — and more economically promising — involves productivity robots: machines built not to replace a missing worker, but to boost overall output and efficiency.
On the autonomous vehicle front, the global market is expected to double to $400 billion over the next five years, with robotaxis set to make their debut on the streets of London as early as 2026. But the real long-term bet is on humanoid robots: by 2050, according to estimates cited by Pictet AM, there could be more than 5 billion of them in operation worldwide, generating a global market worth around $5 trillion. Numbers that dwarf any other technology sector in existence today.
Where to Invest Along the Value Chain
From an investment standpoint, Pictet AM's analysis offers a perspective that cuts against the grain of popular imagination. It is not robot manufacturers that represent the most compelling opportunities — partly because many of them are not publicly listed — but rather the companies supplying the enabling technologies: everything needed to build a robot from the ground up.
The semiconductor content of an average humanoid robot is almost three times greater than that found in an average car. Morgan Stanley estimates that the total potential semiconductor market for humanoids could exceed $300 billion within twenty years. It comes as no surprise, then, that the Pictet-Robotics strategy includes companies such as Keyence and Cognex for machine vision, Nvidia, AMD and Marvell for processing chips, and Infineon and NXP for the analogue semiconductors used in power management and motor control.
The entire value chain — from chipmakers and software companies to sensor manufacturers and semiconductor fabrication equipment suppliers — becomes an ecosystem of opportunity for those looking to position themselves ahead of one of the most durable megatrends of the coming decades.
A Revolution Already Underway
The robotics and artificial intelligence revolution is not a future promise: it is a transformation already in motion, moving faster than many expect. Companies that learn to ride it — and investors capable of identifying the right technology enablers along the value chain — will find themselves in the right place at the right time.
The question is no longer whether robots will reshape the world of work and the global economy. The question is how quickly they will do so, and who will be ready to keep pace.
