The functioning of the brain is often compared to that of a computer. Some researchers are testing this analogy to its limits, attempting to build computers containing lab-grown cultures of brain cells. In doing so, they hope to circumvent the physical limitations of the silicon-based computing hardware used for artificial intelligence today.1,2. The promise is
