Low-tech starts by questioning what we think we need

The limits are not theoretical

Much of today’s technological development is built on an implicit assumption: that resource constraints can be managed, optimized, or eventually overcome. Efficiency gains, new materials, better recycling processes: the narrative of innovation is one of continuous adjustment.

This is where the idea of a circular economy fits in. In theory, materials are reused, waste is minimized, and growth can continue without increasing pressure on resources.

In practice, things are less stable.

Many contemporary technologies rely on complex combinations of materials — rare metals, dispersed components, intricate alloys — that are extremely difficult to recover once used. Recycling is partial, energy-intensive, and often results in a loss of functionality. Some materials are simply dispersed beyond recovery.

These are not marginal issues. They set physical limits. A technology that depends on non-recoverable resources cannot scale indefinitely, regardless of how efficient it becomes.

From this perspective, the question is not whether we can optimize our current systems. It is whether the direction itself is viable.

What are we actually innovating for?

Beyond resources, low-tech introduces a more uncomfortable question.Not how we produce. But why.

The current landscape of innovation offers no shortage of examples: connected devices designed to perform trivial tasks, products adding layers of functionality without clear utility, systems optimized for convenience at the cost of complexity.

A connected juice machine to press pre-packaged fruit. Socks infused with silver nanoparticles to control odor. A connected bikini measuring sun exposure. Automated pet feeders controlled remotely.

These examples are often dismissed as anecdotal. They are not. They reflect a broader orientation: innovation driven by technical possibility and market opportunity, rather than by necessity or collective benefit.

In this context, low-tech is not primarily about simplifying objects. It is about questioning the legitimacy of the needs they respond to. Do we need this product? What does it actually improve? What does it cost, in resources, in complexity, in dependency?

These questions are rarely central in innovation processes. Low-tech makes them unavoidable.

Shifting the terms of innovation

This is why low-tech cannot be reduced to a set of technical solutions. It is a shift in perspective.

It challenges the idea that innovation is inherently desirable, that more technology necessarily leads to better outcomes, that efficiency and productivity are sufficient criteria to guide technological choices.

It also complicates the opposition between low-tech and high-tech.

In practice, the question is not to reject advanced technologies altogether. Some of them create undeniable value: in healthcare, for instance, where imaging technologies or quite complexe medical devices can radically improve outcomes.

The issue is not the level of technology. It is where, how, and for what purpose it is deployed.

In many cases, simpler systems prove more robust, more accessible, and more adaptable. In urban logistics, for example, solutions like electrically assisted cargo trailers can replace short-distance deliveries otherwise carried out by vans, reducing congestion, emissions, and operational costs at the same time. In construction, modular wooden structures designed to be disassembled and reassembled challenge the permanence and waste associated with conventional building methods. In agriculture, approaches based on natural processes, such as using plants to extract excess metals from soils, offer alternatives to energy-intensive remediation techniques.

These examples do not form a unified model, a one-fits-all. They point to different ways of organizing production, use, and value.

What low-tech reveals

Seen from this perspective, low-tech is less a category of technologies than a way of interrogating innovation itself.

It forces a shift from means to ends.

Why do we innovate? Which problems are considered worth solving? Which constraints are taken seriously, and which are ignored?

In a context defined by resource limits and ecological pressures, these questions are no longer theoretical. They determine which systems can persist, and which will eventually fail.

Low-tech does not provide a ready-made alternative. It does something more demanding. It reintroduces the idea that technological choices are not inevitable, and that they can, and should, be debated.
