Will "perfect humans" be born? From "decoding life" to "gene editing"] healthy, smart, beautiful... Can the good qualities that these people aspire to be perfectly integrated into one person? At the beginning of life, the use of gene editing technology can improve the expression and function of genes, reduce congenital diseases, show high-quality traits, and even the birth of "perfect humans" is possible. Some pioneering scientists hope to synthesize a complete human genome within the next 10 years through research. Of course, research involving human genes must undergo rigorous ethical scrutiny. Gene-editing technology cannot currently cross the red line to create "perfect humans."
