That's frightening stuff, but the good news is that this isn't a permanent setback. The findings suggest that there are techniques you could use to beat HIV at its own game, such as making multiple cuts (preventing the virus from easily mutating) or using anti-HIV drugs at the same time as you edit genes. These improvements won't necessarily lead to a cure, but they suggest that HIV's adaptability is more of a temporary obstacle than a permanent barrier. This just serves as a reminder that gene editing is relatively new territory, and there are still many things to learn about how the procedure fares in the real world.
