Why does it matter?
Preventing or curing genetic disease would shift medicine from treatment toward removing inherited burdens.
Direct quote
Very effective prevention and effective cures for genetic disease. Greatly improved embryo screening will likely make it possible to prevent most genetic disease, and some safer, more reliable descendant of CRISPR may cure most genetic disease in existing people. Whole-body afflictions that affect a large fraction of cells may be the last holdouts, however.
