Your brain runs on 20 watts, the same as a dim lightbulb, while the AI systems powering ChatGPT and image generators burn through 50 times more energy doing far less. A company called Unconventional AI just raised 475 million dollars to build chips that run neural networks on physics itself using analog circuits that work like biological neurons, targeting efficiency gains of 1,000 times over current GPUs. The CEO previously sold two AI companies for over a billion dollars combined and walked away from a VP role at Databricks to build this, because AI demand is growing so fast we could literally run out of power to train new models within three to four years.
