When a gene-editing tool like CRISPR can alter human embryos, where should we draw the line between preventing disease and enhancing traits? I'm not talking about obvious cases like sickle cell anemia, but about things like selecting for height or intelligence. The technology moves faster than our ethical frameworks, and I wonder if we're ready for the consequences. Is it ethical to use germline editing for non-medical enhancements, or does that cross a line we shouldn't cross?
