Scientists explore living neurons as the next leap in computing efficiency
While today’s artificial intelligence systems rely heavily on energy-hungry silicon chips, a new frontier is emerging that could radically shift the way we think about computing.
This frontier doesn’t rely on metal or code—it’s built from living human neurons.
The Biological Turn in Computing
Across the globe, researchers are racing to construct biocomputers powered by cultivated nerve cells.
At the forefront is Swiss company FinalSpark, where neuroscientist Dr. Ewelina Kurtys and her team are cultivating networks of human neurons to function as “living processors.” These systems, though still in their infancy, could eventually surpass the energy efficiency and learning capacity of today’s machines.
Dr. Kurtys explained in an interview:
We are working on computers from living neurons because nerve cells are very energy efficient,
Their lab maintains around 10,000 neurons on culture plates, forming a network that can be trained using electrical impulses.
The key lies in mimicking the brain’s natural communication system. Neurons in these experimental setups are linked to electrodes, enabling them to send and receive signals much like the human brain does.
Early experiments have already allowed the team to store a single bit of information in this organic network—a milestone signaling the viability of the concept, as reported by WP Tech.
A New Layer, Not a Replacement
Despite the excitement, biocomputers aren’t expected to fully replace silicon-based processors.
I see a future where different technologies will be used simultaneously, for different purposes,
Dr. Kurtys
While bioprocessors may handle complex, adaptive tasks more efficiently, conventional computers will continue to serve high-speed, high-volume processing needs.
Other companies are experimenting too. Australia’s Cortical Labs has trained living cells to play ‘Pong,’ demonstrating the neural network’s potential for interactive learning.
Toward a Living AI Infrastructure
Although current prototypes are limited in scope, the ambitions are enormous. FinalSpark’s vision includes developing a functioning biocomputer within a decade—one that could generate over a billion dollars in annual profit.
If successful, this fusion of biology and technology could usher in an entirely new era for artificial intelligence.
As the first neural bits are recorded, humanity may be witnessing the quiet dawn of a living, thinking machine.
