It’s hard to ignore the contradiction at the heart of modern computing: We build ever-more robust AI systems while burning more energy to run them. As generative AI booms and cloud usage expands, data centers expand and more electricity is needed. With each leap in intelligence, we double down on a system that threatens to overheat globally. So what if the future of computing wasn’t silicon? What if it were alive?

Fred Jordan, physicist and founder of FinalSpark, is doing more than asking the question. His team is answering it by working to build the first living processors. These systems use real human neurons, cultivated from stem cells, to perform computation. That means replacing digital simulations with biological brains-on-a-chip. It’s an entirely new category of computing, and designed to solve AI’s energy problem. Fred walks us through how it works, why it matters, and where this frontier could take us.

Conclusion: 

Fred Jordan isn’t building faster computers—he’s building different ones. By growing neurons and training them to compute, he’s laying the groundwork for a future where biology replaces transistors in parts of our digital world. It’s still early, but the implications are enormous. In an era defined by data and electricity, Final Spark’s approach offers something radical: intelligence that doesn’t drain the grid.
