Genetic engineering will extend human lifespan from "summary" of The Singularity is Near by Ray Kurzweil
One of the key drivers of human evolution in the coming decades will be our ability to manipulate our own genetic code. Genetic engineering has already made significant strides in treating various diseases, but its potential goes far beyond that. By understanding the genetic basis of aging and disease, we can begin to intervene in the aging process itself. Scientists have identified a number of genes that are involved in aging, and by manipulating these genes, it may be possible to extend the human lifespan significantly. For example, researchers have found that reducing the activity of the gene IGF-1 in mice can increase their lifespan by up to 33 percent. This suggests that similar interventions in humans could have a similar effect. Furthermore, advances in biotechnology are making it increasingly feasible to edit the human genome with precision. The CRISPR-Cas9 system, for example, allows scientists to make targeted changes to specific genes with unprecedented accuracy. This o...
