LAST HUMANS BORN BY CHANCE

[00:00:00]Your grandkids might be the last humans ever born by chance. Everyone after them will be chosen. Right now, in real labs, scientists are turning normal skin cells into eggs and sperm. It's called in vitro gametogenesis, and it quietly breaks one of the oldest rules of being human. Because once you can grow a sperm or an egg from a skin cell, you can edit it first with CRISPR before there's even a baby. They go in and change specific genes one by one. The medical side is amazing. It can remove diseases you would pass to your kids. It can take out the cancer risk in your family before the child is even born. Some labs have already made embryos that can't get HIV.

[00:00:34]But here's the part that stopped me cold. This same tech means a same-sex couple could one day have a baby that's fully theirs, made from both of them.

[00:00:41]Something that was never possible in the entire history of life on Earth.

[00:00:45]Honestly, this is the kind of thing that keeps me up at night, and there's a lot of it on my page. But that same technology has another side. It can also just choose things, like eye color or height, maybe things we don't even say out loud yet. And it's moving faster than any law can catch it. Some scientists think it's only 10 years away from a normal clinic. So here's the real question. The day you actually could design your child, where would you stop?
