# Computers using brain organoids raise ethical concerns researchers are ignoring

Researchers are building computers that run on clusters of lab-grown brain cells (organoids). However, they have neglected a major ethical issue: whether these organoids could develop consciousness or experience suffering. This gap in consideration matters as it blurs boundaries between computing and biology, raising new bioethics questions.
