Biocomputers: Scientists are turning human brain cells into functional computers

SMRTR summary

Scientists are developing biocomputers using living human brain cells grown into clusters called organoids, which are connected to electrodes to perform computational tasks like playing Pong and recognizing speech patterns. These biological systems could revolutionize computing by using dramatically less energy than traditional computers, requiring only 20 watts compared to millions needed by supercomputers.
