If genetic engineering is used to change the genes of a baby by "germline" editing, then...
1) the world will likely end.
2) that baby will be born infertile.
3) that baby will have either laser eyes, telepathy, or retractable metal claws.
4) that baby will eventually be able to pass on its new genes to its own offspring.
5) that baby will not be able to pass on its new genes to its offspring.
