If only genetic engineering is well understood enough to be applied in medical field, introducing a viral vector and able to target the mutation site with high efficacy would save lifes btw, IMHO GM foods are needed by those poor countries in large amounts as they're richer in nutritions and imagine the world without GE, the silk prices will hike up like hell. GE FTW!

Mutations can be good or bad. Such as mutation to the CCR5 gene protects some gay community fellas from being infected by HIV
