Too cheap to matter: over abundant microchips, and what we can learn from them
This paper examines the environmental and societal costs of ultra-cheap, overabundant microchips that drive unnecessary obsolescence and e-waste, while calling on the LOCO community to develop skills and strategies for creating lasting, sustainable technology.

Most people think of the digital world as something that lives in screens, servers, and the cloud. We imagine it as a vast, invisible network of information that powers our lives. But there is another side to this story, one that is physical, tangible, and hidden in plain sight. It is the story of the tiny silicon chips that have become so cheap and plentiful they are no longer just components; they have become a kind of raw material, like plastic or glass, that is built into almost everything we touch. These are the microchips found in toys, kitchen appliances, and even single-use items. They are so inexpensive that they cost less than a dollar, yet they are produced in such staggering numbers that they account for the vast majority of the hundreds of billions of chips sold every year. While the world focuses on the most powerful, expensive chips that drive artificial intelligence, a different, quieter reality is unfolding: a world of "smart" objects that are designed to be used briefly and then thrown away. This phenomenon raises a difficult question about how we build our future, what we throw away, and whether we are creating a mountain of waste that we cannot see.
A team of researchers recently gathered to investigate this hidden layer of our technological landscape. They wanted to understand the true cost of these ultra-cheap microchips, not just in money, but in the materials they consume and the waste they generate. Their work began with a simple observation: as technology advances, the newest, most complex chips get all the attention. However, the older, simpler generations of these chips are still being manufactured in massive quantities. In fact, chips designed decades ago are still being produced today because the factories that make them are already built and the costs are incredibly low. This creates a situation where billions of these tiny devices are embedded into everyday items, turning simple objects into "smart" ones, often without any real need for that intelligence. A toaster might have a chip to sense when the bread is done, or a child's toy might have one to make it talk. The researchers argue that this abundance has led to a culture of "fast tech," where products are made to be disposable. Because the chip inside costs so little, the entire product becomes cheap enough to discard after a short life, contributing to a growing crisis of electronic waste.
To get a closer look at what is actually happening inside these devices, the researchers organized a workshop where they took apart a variety of low-cost items. They examined a digital pregnancy test, a broken bike light, a battery charger, and several cheap children's toys. Their goal was to see what was inside, where it came from, and whether it could be used again. What they found was surprising. Inside these seemingly simple objects were sophisticated microcontrollers, the small brains that run the device. In one case, a disposable electronic cigarette contained a chip powerful enough to run a web server if someone knew how to reprogram it. These chips are not just simple switches; they are capable computers, yet they are treated as disposable trash. The researchers noted that these chips are often so cheap that manufacturers do not bother to label them clearly, making it nearly impossible to identify what they are or how to use them. In some toys, the chip is buried under a blob of resin, a protective coating that seals it in so tightly that removing it would destroy the chip. This design choice is deliberate; it keeps the cost down but ensures the part cannot be recovered or reused.
The team also looked at the broader picture of how these chips are made and where they end up. They found that the industry relies on a cycle where older, proven manufacturing methods are used to produce these chips at a massive scale. This allows for production volumes that are hard to imagine, with hundreds of billions of units sold annually. However, this efficiency comes with a heavy environmental price. The materials needed to make these chips, including rare metals and exotic elements, are extracted from the earth and then discarded when the products are thrown away. The researchers pointed out that electronic waste is now the fastest-growing waste stream in the world, with a significant portion coming from these small, low-cost devices. Much of this waste ends up in countries where it is burned or treated with harsh chemicals to extract valuable metals, causing severe harm to the environment and the people living there. Despite the fact that these discarded devices contain a concentrated source of valuable materials, the current system makes it too difficult and expensive to recover them.
The researchers conclude that the problem is not just about recycling; it is about how we design and value our technology. They suggest that the industry has created a system where the true cost of these chips is hidden. The price tag on a product does not reflect the environmental damage caused by its creation or its disposal. To fix this, they argue that we need to change how we think about these materials. Instead of seeing them as disposable, we should view them as a resource that needs to be preserved. This means designing products that last longer, making it easier to repair them, and creating systems that allow us to recover the valuable materials inside. The researchers also call for better education, urging engineers and designers to learn how to work with these existing devices and find new ways to use them before they become waste. They believe that if we can make the invisible visible, we can start to build a future where technology serves us without leaving a trail of destruction behind. The challenge is to move away from a model of endless consumption and toward one of sufficiency, where we produce only what we truly need and ensure that what we make can be used for a long time.
