The web’s subsequent existential disaster gained’t be disinformation or deepfakes. It will likely be copper.
The world is constructing AI prefer it’s Minecraft, stacking data centers, transmission traces, and cooling methods with little regard for the bodily limits beneath them. Everybody is targeted on fashions and computation, however few acknowledge the steel that makes them run.
Each piece of recent electrical infrastructure—not simply AI—is dependent upon copper. AI data centers are merely accelerating demand. One hyperscale facility can require tens of 1000’s of tonnes of copper. For instance, one Microsoft knowledge middle used over 2,000 tonnes, or 27 tonnes per megawatt. A McKinsey report predicts that total transmission build-out might push annual world copper demand as much as about 37 million tonnes by 2031.
Accessible copper is running out. Greater than 70 p.c of worldwide reserves are locked in ores that standard mining struggles to course of effectively. Tens of billions of tons sit idle in waste piles and marginal deposits, ignored by trade however nonetheless wealthy with potential.
That potential is what drew me right here. As a geoscientist who later labored in vitality and cloud infrastructure, I noticed firsthand the rising want for copper—and realized I had the information to assist tackle it. In 2023, I based a startup referred to as Endolith to recuperate copper from these forgotten sources. The instrument just isn’t drills or dynamite. It’s microbes.
How microbial mining works
These microbes are naturally advanced, field-deployable, and extremely efficient at recovering copper from complicated ores similar to chalcopyrite and enargite. They thrive in leaching heaps below real-world situations, working with actual prospects. And the bonus: They use much less vitality, ship extra copper, and have a smaller environmental footprint than conventional strategies.
And what are these conventional strategies? Usually, mines extract copper from ores by grinding the rock, concentrating the ore, after which utilizing high-temperature smelting or chemical leaching with robust acids. Each approaches are energy-intensive, gradual to unlock copper, and go away behind giant volumes of waste and emissions.

In distinction, our “microbial minions” work by accelerating the pure strategy of bioleaching. As a substitute of counting on smelting or harsh acids, Endolith’s microbes connect to the ore and pull out the copper quicker. They adapt to the chemistry of various rock varieties, recuperate extra steel, and do it with decrease vitality use and fewer environmental impression.
To make this doable, we depend on machine studying. Genomic and metabolic knowledge from 1000’s of microbes are modeled to foretell which strains can survive in excessive ores similar to chalcopyrite or enargite, and the way they may carry out below totally different environmental situations. These fashions information which microbial communities are deployed, how they’re tuned for every website, and the way they adapt over time. In impact, AI is what turns biology from trial-and-error right into a scalable system for copper restoration; in flip, that copper is what retains powering the expansion of AI itself.

Our method has already been validated by a few of the largest copper producers on this planet, including BHP. Microbial restoration is cleaner. It scales. It adapts. Our modular biohatcheries—area items designed to develop and ship tailor-made microbes—may be deployed in days. They are often tuned for native situations. They make copper restoration viable on deposits that have been beforehand left untouched. This instrument opens entry to part of the supply chain that mining has ignored and expertise has not often thought-about.
The copper crunch is slowing down AI
Conversations about AI infrastructure not often tackle this layer. Computing prices and vitality wants dominate the narrative, but copper underpins your entire system.

The bodily aspect of AI is usually hidden from view. Its presence turns into apparent when a knowledge middle challenge is delayed as a result of a transformer can’t be delivered on time, or when utilities can’t construct transmission traces shortly sufficient to help new computing hundreds. These are copper issues, hiding in plain sight.
I’ve had calls with website engineers who’re enthusiastic about deploying cutting-edge computing, however are quietly anxious about whether or not the wiring can deal with it. Infrastructure doesn’t mechanically comply with as a result of the software program is prepared. Copper is sure by geology and time. Mines transfer slowly, recycling strikes too narrowly, and demand strikes too quick. Smarter organic restoration is the lever we are able to pull at present.
Skeptics observe that bioleaching has traditionally struggled with robust ores like chalcopyrite. Processes have been usually gradual, incomplete, or troublesome to handle at scale. Current advances in microbial science and heap engineering are closing these gaps. With AI guiding the optimization of microbes, we are able to now match the appropriate strains to the appropriate ores, displaying that biology can succeed the place older strategies fell quick.
Too usually, expertise assumes the fabric world will maintain tempo with ambition. However ambition alone can’t dig rock from the bottom—and it undoubtedly can’t create copper. I see a disconnect between perception and infrastructure. We imagine this future is coming, however the bodily methods required to help it are a long time behind. If we need to construct one thing sturdy, we’d like greater than ambition and venture capital. We want steel, and we’d like smarter pathways to extract it.
If we need to maintain constructing, we have to be clear about what we’re constructing with. Which means extraction, wiring, and chemistry—the elements of the system that not often make headlines however decide whether or not progress is feasible.
The AI period is not going to be sustained by pleasure. It will likely be sustained by copper. And the subsequent leap in restoration might come from microbes…tiny, historical, and alive.
