You’re not “renting a brain” — you’re renting biological computation. 🧠⚡ Companies like FinalSpark and Cortical Labs are working in the field of neuromorphic & biocomputing, where living human neurons (grown from stem cells) are cultured into brain organoids and connected to electrodes. These neurons process information using the same electrochemical signaling your brain uses — action potentials, synaptic plasticity, and adaptive learning — but in a lab-controlled environment. Why this matters: • Neurons are orders of magnitude more energy-efficient than silicon • They naturally learn through Hebbian learning (connections strengthen with use) • They operate asynchronously, unlike clock-driven CPUs • They blur the line between hardware and software FinalSpark’s model lets researchers remotely send electrical stimuli to neuron clusters and read responses — effectively using living tissue as a compute substrate. Cortical Labs, on the other hand, embeds neurons directly into hardware s...
